ADCs Architecture: Delta-Sigma
delta-sigma ADC, input signal oversampled modulator high sampling rate, then filtered decimated produce high-resolution data stream digital filter lower sampling rate. Deltasigma converters capable very high accuracy, ideal converting signals which range frequency from several megahertz. delta-sigma architecture approach allows resolution traded speed both traded power. This nearly continuous relationship between data rate, resolution, power consumption makes delta-sigma converters extraordinarily flexible. many delta-sigma converters, this relationship programmable, allowing single device handle multiple measurement requirements. Because delta-sigma converters oversample their inputs, they perform most antialiasing filtering digital domain. Modern VLSI design techniques have brought cost complex digital filters below cost their analog equivalents. Formerly unusual functions, such simultaneous 50/60Hz notch filtering, built into delta-sigma ADCs costing less than equivalent SAR-based system with analog filtering. Typical high-resolution applications delta-sigma ADCs include industrial process control, analytical test instrumentation, medical instrumentation, digital audio.
Design Considerations
Sampling Rate number times second input signal sampled. most types data converters, this rate also rate which samples delivered. delta-sigma converters, sampling rate usually much higher than "data rate. Data Rate number samples delivered second. Delta-sigma converters sample input many times deliver single oversample data point. rate which they sample signal called "sampling rate. delta-sigma converters, data rate usually much lower than sampling rate, while some data rate programmable. Decimation Ratio ratio between sampling rate data rate. Many delta-sigma converters allow decimation ratio adjusted. Higher decimation ratios result lower data rate, also lower noise. Decimation ratio sometimes called "oversampling ratio. Filter settling Time delta-sigma converters normally measure continuous bandlimited waveform. When delta-sigma converter encounters very rapidly changing input signal, such step waveform, digital filter goes through process called "settling. Settling occurs because filter's output cannot change quickly input can. During settling, filter's output approaches, eventually reaches, input level.
amount time takes filter settle usually expressed terms "conversion cycles. filter that settles four cycles produces most three invalid data points when given step input. Different filter types have different settling characteristics. example, sinc5 filter settles five cycles; sinc1 filter settles cycle. Some digital filters settle cycle. Settling time important consideration multiplexing designs. delta-sigma's filter must settle each time channel delta-sigma converter changed, since this usually results step input. ENOB acronym "Effective Number Bits, expressing data converter's inherent signal-to-noise ratio. ENOB term; converter with ENOB 19-bits 19-bits "noise free. Noise-Free Bits certain number data converter's most significant bits will remain constant input signal. These bits called "noise-free bits" measure converter's peak-topeak noise. Modulator Frequency rate which modulator processes input signal. Usually, always, modulator frequency equals sampling rate. Noise Shaping special characteristic delta-sigma modulator. Delta-sigma modulators quantize input signal into low-resolution, high-rate data stream which special property: unlike normal sampling systems, most quantization noise appears high-frequency noise. This highfrequency noise filtered digitally produce converter's output. Noise shaping gives delta-sigma converter important advantage over other kinds oversampling systems: thanks noise shaping, higher resolution obtained given oversampling ratio.
Delta-sigma ADCs consist delta-sigma modulator followed digital decimation filter. modulator incorporates comparator integrator feedback loop with DAC. loop synchronized clock.

Delta-Sigma ADCs
Modulator Order simplest kind delta-sigma modulator "first-order modulator" Higher order modulators shape quantization noise more strongly, producing less noise sampling bandwidth. However, high-order modulators more difficult design, consume more power, take more chip space. very low-power low-speed devices, first- second-order modulators most common. Low-noise high-performance devices typically third-, fourth-, fifthorder modulators. Some converters, particularly audio devices, networks multiple modulators achieve high speeds very noise, with corresponding increase power size. voltage ground. differential input structure delta-sigma makes ideal measuring differential sources such bridge sensors thermocouples. Frequently, input amplifiers required these applications. Delta-sigma converters work differently than converters. takes "snapshot" input voltage analyzes determine corresponding digital code. delta-sigma watches input signal certain period time outputs digital code corresponding signal's average over that time. important remember delta-sigma converters operate, particularly designs incorporating multiplexing synchronization. very easy synchronize delta-sigma converters together, that they sample same time, it's more difficult synchronize delta-sigma converter external event. Delta-sigma converters highly resistant system clock jitter. action oversampling effectively spreads jitter across frequency spectrum, making part noise floor. Many delta-sigma converters include "input buffers" "PGAs. input buffer increases input impedance allow direct connection high source impedance signals. (programmable gain amplifier) increase converter's resolution when measuring small signals. Bridge sensors typical signal sources that take advantage within converter. Every requires reference, high-resolution converters, low-noise, low-drift references critical. Most delta-sigma converters have differential reference inputs.

ADCs Architecture: SASuccessive-approximation register (SAR) converters frequently architecture choice medium-to-high-resolution applications with medium sampling rates. ADCs range resolution from 18-bits with speeds typically less than 10MSPS. They provide power consumption small form factor. converter operates same principle balance scale. scale, unknown weight placed side balance point, while known weights placed other side rejected kept until sides perfectly balanced. unknown weight then measured totaling kept, known weights. converter, input signal unknown weight, which sampled held. This voltage then compared successive known voltages, results output converter. Unlike weigh scale, conversion occurs very quickly through charge redistribution techniques. Because samples input signal holds sampled value until conversion complete, this architecture does make assumptions about nature input signal, signal therefore does need continuous. This makes architecture ideal applications where multiplexer used prior converter, applications where converter only need make measurement once every seconds, applications where "fast" measurement required. conversion time remains same cases, little sample-to-conversion latency compared pipeline converter. converters ideal real-time applications such industrial control, motor control, power management, portable/battery-powered instruments, PDAs, test equipment data/signal acquisition.
Design Considerations
Acquisition Time time takes internal sample-and-hold amplifier acquire signal settle converter's resolution. Conversion Time time takes converter convert sampled signal into digital result. This typically clock cycles converter, where number bits resolution. Throughput Rate maximum rate which signals acquired converted. This usually found adding acquisition conversion times. Usually expressed terms frequency, such 100,000 samples second. Missing Codes converter with greater than 1LSB negative differential nonlinearity adjacent codes would result code potentially never occurring output-it would "missing code. Ideally, con" verter with bits resolution bits missing codes. Internal/External Clock clock that controls conversion process built-in converter externally provided user. Using external clock allows user potentially
slow down clock during acquisition time converter, thereby extending this time increasing accuracy because input more time settle. external clock also allows conversion process synchronous other functions system. Internal clocks allow data conversion occur asynchronously, data from conversion read processor more convenient time. Bipolar/Pseudo-bipolar Inputs Many modern converters operate only from single power supply, only accept input signal levels that swing between supply. many applications, output coding converter still needs appear though signal bipolar. Converters that this said bipolar, when fact they "pseudo-bipolar": input signal cannot swing below ground, instead swings around point that one-half supply voltage, around reference voltage. important user aware this when choosing converter, choose that really does what desired. input signals must swing bipolar around ground, then choose converter whose input range explicitly stated that.
ADC, bits decided single high-speed, high-accuracy comparator bit, from down LSB. This done comparing analog input with whose output updated previously decided bits successively approximates analog input.

Technical Information
Modern ADCs sample capacitor that charged voltage input signal. ADC's input capacitance, input impedance, external circuitry, settling time will required sample capacitor's voltage match measured input voltage. Minimizing external circuitry's source impedance minimize this settling time, assuring that input signal accurately acquired within ADC's acquisition time. more troublesome design constraint, however, dynamic load that ADC's input presents driving circuitry. driver input must able handle this dynamic load settle desired accuracy within required acquisition time. ADC's reference input circuitry presents similar load reference voltage. While reference voltage supposed very stable voltage, dynamic load that ADC's reference input presents makes achieving this goal somewhat difficult. Thus, buffer circuitry required reference voltage, used this similar requirements that used driving input; fact, requirements even higher than input signal. Some ADCs feature internal reference buffer. Buffering these inputs using amps with low, wideband output impedance best preserve accuracy with these converters.

ADCs Architecture: Pipeline
Analog-to-Digital converters featuring sampling rates 10's MSPS likely based pipeline architecture. pipelined consists cascaded stages. concurrent operation pipeline stages makes this architecture suitable achieving very high conversion rates. stages themselves essentially identical, lined assembly line fashion designed convert only portion analog sample. digital output each stage combined produce parallel data output bits. digitized sample becomes available with every clock cycle. internal combination process itself requires digital delay, which commonly referred pipeline delay, data latency. most applications this limitation since delay, expressed number clock cycles, constant accounted for. architectural features pipeline ADCs that allows high dynamic performances high signal frequencies differential signal input. differential input configuration results optimum dynamic range since leads smaller signal amplitude reduction even-order harmonics. Almost high-speed pipeline ADCs single supply voltage, ranging from down +1.8V. Therefore, most require analog input operate with common-mode voltage, which typically mid-supply level. This commonmode input bias requirement comes into consideration when defining input interface circuitry that will drive ADC. Switched capacitor inputs should also considered. clock cycles from time sample acquired until available ADC's digital output. Analog Input Bandwidth bandwidth which spectral power fundamental frequency, applied pipeline converter input, reduced below full-scale. This typically determined analysis. SFDR (Spurious Free Dynamic Range) distance from fundamental amplitude peak spurious component output frequency spectrum. peak spur either harmonic non-harmonic nature. (Signal-to-Noise Ratio) ratio signal's value value other spectral components, excluding first five harmonics Specified dBFS particular fundamental frequency sampling rate. SINAD (Signal-to-Noise Distortion) ratio signal power power spectral noise harmonic components within Nyquist bandwidth. Specified dBFS particular fundamental frequency sampling rate. Aperture Jitter phase modulation sampling clock causing sampleto-sample variation exact moment amplifier acquires sample. Aperture jitter characterizes ADC's ability accurately digitize rapidly changing input signals. This becomes important consideration undersampling applications.

This most critical blocks typically sets performance limits converter. captured sample passes through pipeline, conversion iterated stages that refine conversion with increasing resolution they pass remainder signal from stage stage. Each stage performs analog-to-digital

Furthermore, dynamic since function sampling rate (1/fs). internal switches generate small transient current pulses that affect settling behavior source. reduce effects this switchedcapacitor, input series resistors shunt capacitor typically recommended. This will also ensure stability fast settling driving amplifier. select appropriate interface circuit configuration, important determine whether application time domain nature (e.g. CCD-based imaging system) frequency domain application (e.g. communication system). Time domain applications usually have input frequency bandwidth that includes Frequency domain applications, other hand, typically ac-coupled. converter specifications here SFDR, SNR, aperture jitter analog input bandwidth; last specifications particularly apply undersampling applications. optimum interface configuration will depend whether application calls wide dynamic range (SFDR), noise (SNR), both.

Pipeline ADCs both rising falling clock edge trigger internal functions. example, sampling occurs rising edge prompting this edge have very jitter. Clock jitter leads aperture jitter, which ultimate limitation achieving good performance. Particularly undersampling applications, special consideration should given clock jitter.

DACs Architecture: String R-2Resistor "String" R-2R DACs consist four major elements: logic circuitry, some type resistor network, means switching either reference voltage current proper input terminals network function digital value each digital input reference voltage. Integral Nonlinearity (INL) Error deviation values actual transfer function from straight line. This straight line either best straight line, which drawn minimize these deviations, line drawn between points transfer function once gain offset errors have been nullified. second method called end-point linearity usual definition adopted since verified more directly. deviations measured transitions from step next, they measured each step. name integral nonlinearity derives from fact that summation differential nonlinearities from bottom particular step, determines value integral nonlinearity that step. Dynamic Characteristics those characteristics errors that affect behavior during transitions, which described just four terms. These settling time, glitch, feed through noise. Settling Time defined time required output approach final value within limits defined error band, step change digital input. There some important distinctions, which must mentioned when discussing settling time specifications. settling time error band described ±1/2LSB converter with full-scale, then 12-bit allowable error band ±0.601mV 16-bit error band ±0.038mV. Thus 16-bit device necessarily slower than Resistor matching improves accuracy.
VREF
12-bit device, simply requires more time settle tighter specification. Therefore, comparing settling time between DACs same resolution, important know specified error band. Glitch discussion settling time, total time transients settle considered, nature these transients. glitch defined amount charge injected into analog output from digital inputs when inputs change state. typically measured half scale input codes where many possible switches change state from 7FFF 8000 HEX. Glitch effects create different problems depending application. example, graphics positioning systems, amplitude glitch important. control systems, total energy important total energy glitch transient zero, then effect glitch could removed filtering. Digital Feedthrough When selected, high frequency logic activity digital inputs coupled through device shows output noise. This noise digital feedthrough. Total Harmonic Distortion Noise defined ratio square root squares values harmonics noise value fundamental frequency. expressed percent fundamental frequency amplitude specific update rate
Design Considerations
Static Errors those errors that affect accuracy converter signals described four terms: offset error, gain error, integral nonlinearity differential nonlinearity. Each expressed units sometimes percentage FSR. example, error 1/2LSB 12-bit converter corresponds 0.012% FSR. Offset Error defined difference between nominal actual offset points. ADC, offset point midstep value when digital output zero, step value when digital input zero. This error affects codes same amount usually compensated calibration. Gain Error defined difference between nominal actual gain points transfer function after offset error been corrected zero. ADC, gain point midstep value when digital output full scale, step value when digital input full scale. This error represents difference slope actual ideal transfer functions such corresponds same percentage error each step. This error also usually adjusted zero calibration Differential Nonlinearity (DNL) Error difference between actual step width (for ADC) step height (for DAC) ideal value 1LSB. Therefore, step width height exactly 1LSB, then differential nonlinearity error zero. exceeds 1LSB, there possibility that become non-monotonic. This means that magnitude output gets smaller increase magnitude input.

DACs Architecture: Current Steering
Modern high-speed digital-to-analog converters, fabricated submicron CMOS BiCMOS processes, have reached performance levels with update rates 500MSPS resolutions even 16-bit. order realize such high update rates resolutions, DACs employ current-steering architecture with segmented current sources. core element within monolithic current source array designed deliver full-scale output current, typically 20mA. internal decoder addresses differential current switches each time updated. Steering currents from current sources either differential outputs forms corresponding signal output current. Differential signaling used improve dynamic performance while reducing output voltage swing that developed across load resistors. Ideally, this signal voltage amplitude should small possible maintain optimum linearity digital-to-analog converter. upper limit this signal voltage consequently load resistance defined output voltage compliance specification. segmented current-steering architecture leads significant reduction circuit complexity consequently reduced glitch energy. This translates into overall improvement DAC's linearity performance. system architectures require synthesis output frequencies MHz, approach often referred "direct-IF" achieves high update rates while maintaining excellent dynamic performance.
Design Considerations
Update Rate rate which Digital-to-Analog converter changes signal output result update internal latch. Often, update rate equivalent applied clock frequency. Output Voltage Compliance, current-output DAC, maximum (output) voltage that develop output terminals which device will provide specified performance. Exceeding compliance limit will cause nonlinear performance resulting rapid increase signal distortion. Glitch Impulse time domain specification describing switching transient occurring output during code change. Glitch impulse specifies time integral (area) analog value glitch transient, usually provided units pV-sec.
ACPR Adjacent Channel Power Ratio compares signal power transmitted in-band power leaking into adjacent (out-of-band) channels. relates regulatory requirements meeting certain spectral mask total transmitted power. Intermodulation Distortion (IMD) two-tone ratio either fundamental tone worst order higher) product. Typically, order harmonic products dominant with their location close fundamental they difficult filtered out. Sinx/x Roll-off with digital-to-analog converter being sampled system, sinx/x roll-off describes attenuation output spectrum resulting from DAC's zero-order hold response.

Special Function Data Converters: MicroSystems
MicroSystem products combine well established microcontroller core, with best-of-class analog performance. microcontroller core analog core integrated together with highperformance peripherals make highly integrated system solution. Therefore, MicroSystem products well with applications that require high analog performance high integration. Integration plays critical role highprecision systems. Integration solve technical problems such reducing system level performance problems, noise, interference, interface layout issues. Integration also reduce research development time simplifying parts search, prototyping, design. Furthermore, performance parameters system localized, making development debug more efficient. benefit more robust, reliable predictable system. technical information design considerations analog cores, described other sections, which integrated into MicroSystem product, still apply. However, MicroSystem products offer increased flexibility controlling these parameters meet specific needs application. instance, with delta-sigma ADC, modulator clock controlled directly make speed versus resolution trade offs. This makes MicroSystem product powerful, customizable solution.
Technical Information
most systems, analog data cannot used directly from converter, must processed. microcontroller with analog makes processing this data possible. amount type processing depends application. instance, 8051 microcontroller widely used industrial applications. This fact that architecture good match many industrial applications, there wide variety support tools, core been industry very long time. analog side, delta-sigma been widely used industrial applications fact that provides highest accuracy measurement converter. However, combining these cores demonstrates some integration problems with high-performance systems. 8051 8-bit data bus, whereas many delta-sigma ADCs have 24-bit result. accessing data requires three distinct data transfers. addition, data processing requires even more bandwidth from CPU. MicroSystem products solve these problems through methods. first method with faster instruction cycle. instruction cycle time three times faster than standard 8051 instruction cycle. second method through implementation 32-bit accumulator, which accessed either CPU. This allows results manipulated independently through accumulator, which improves efficiency data manipulations. This greatly increases overall system throughput data manipulation, such averaging filtering. benefit that real processing throughput MicroSystem products much higher than what MIPS device would indicate.
Additional flexibility offered with memory. SRAM mapped into data memory shared with program memory (von-Neumann). on-chip Flash memory mapped into either program data memory space. Hence, endurance been increased accommodate data memory. addition, Flash memory programmed through parallel interface, serial interface, directly user application code. direct user application feature made possible unique ability MicroSystem product modify program memory. Once data processed, then information transferred either analog output digital output. MicroSystem family offers linear outputs analog output control. digital output, data transferred serial interface. Serial interfaces robust. supports transfer rates external clock speed. through FIFO which provides more efficient data transfers without requiring overhead. list analog features MicroSystem products long: ADC, DAC, multiplexer, burn-out detect, selectable buffered input, offset DAC, PGA, precision on-chip voltage reference, on-chip temperature sensor, voltage detect, brown-out reset. list digital features includes CPU, Flash memory, SRAM, multiple ports, external memory capability, 32-bit accumulator/shifter, dual UARTs, timers/counters, SPI, watchdog timer.

Precision Analog: Voltage References
Primary Design Considerations
Topologies Shunt (two-terminal) Series (three-terminal). Shunt references very similar Zener diodes operation both require external resistor biasing. external resistor determines maximum current that supplied load. Shunt references should considered when load nearly constant power supply variations minimal. Series references require external components they should considered when load variable lower voltage overhead important. They also more immune power supply changes than shunt references. Temperature Drift Temperature drift change output voltage temperature change, expressed ppm/°C. Buried Zener type references (e.g., REF02, REF102) typically have lower temperature drift than bandgap type voltage references. Temperature drift specified several ways (slope, butterfly box) most common method calculated (Vmax Vmin) (Tmax Tmin) Vnom Output Noise Output noise usually specified over frequency ranges: 0.1Hz 10Hz (peak-to-peak noise) 10Hz 1kHz (RMS noise). Noise important because reduce dynamic range acquisition system. High-resolution data acquisition systems experience "dither" LSBs solely reference noise. Noise reduced external filtering (REF102 noise reduction pin).
Secondary Design Considerations
Initial Accuracy This parameter importance systems where calibration impossible inconvenient. Usually, accomplished calibration overall system. Initial accuracy specified with fixed input voltage load current (for series type) fixed bias current (for shunt type). Long-Term Stability output voltage reference changes gradually time goes greatest change occurs first 500hr. This parameter important high-performance applications applications where periodic calibration acceptable. specifies long-term stability data based observation over 1000hr room temperature.
Technical Information
Both fixed adjustable outputs available. Adjustable output resistor divider connected reference pin. Shunt references regulators require minimum biasing current maintain regulation. Available packages include throughholes PDIP TO-92, along with surface mount SOIC, TSSOP SOT89 SOT23.
