Many applications benefit from choosing much wider bandwidth/slew rate achieve distortion, excellent linearity, good gain accuracy, gain flatness other behavior that influenced feedback factors. Power requirements)-a significant issue many applications. Because amps have considerable impact overall system power budget, quiescent current, especially battery-powered applications, design consideration. Rail-to-rail performance-rail-to-rail output provides maximum output voltage swing widest dynamic range. This particularly important with operating voltage where signal swings limited. Rail-to-rail input capability often required achieve maximum signal swing buffer (G=1) single-supply applications. useful other applications, depending amplifier gain biasing considerations. Voltage noise (VN)-amplifier-generated noise limit ultimate dynamic range, accuracy resolution system. Lownoise amps improve accuracy, even slow measurements. Input bias current (IB)-can create offset error reacting with source feedback impedance. Applications with high source impedance high impedance feedback elements (such transimpedance amplifiers integrators) often require input bias current. FET-Input CMOS amps generally provide very input bias current. Slew rate-the maximum rate change amplifier output. important when driving large signals high frequency. available large signal bandwidth determined slew rate SR/.707(2p)VP Package size-TI offers wide variety microPackages, including WCSP, SOT23, SC70 small, high power-dissipating PowerPADpackages meet space-sensitive high-output drive requirements.

Technology Primer
Understanding relative advantages basic semiconductor technologies will help selecting proper device specific application. CMOS Amps-when voltage and/or power consumption, excellent speed/power ratio, railto-rail performance, cost small packaging primary design considerations, choose microPackaged CMOS amps boasting highest precision industry. High-Speed Bipolar Amps-when highest speed lowest power required, bipolar technology delivers best performance. Extremely good power gain gives very high output power full power bandwidths lowest quiescent power. Higher voltage requirements also only satisfied bipolar technologies. Precision Bipolar Amps-excel limiting errors relating offset voltage. These amps include offset voltage temperature drift, high open-loop gain common-mode rejection. Precision bipolar amps used extensively applications where source impedance low, such thermocouple amplifier, where voltage errors, offset voltage drift, crucial accuracy. Amps-when input impedance very high, FET-input amps provide better overall precision than bipolar-input amps because very input bias current. Using bipolar applications with high source impedance (e.g., 500M probe), offset, drift noise produced bias currents flowing through source would render circuit virtually useless. When current errors required, amps provide extremely input bias current, offset current high input impedance. Dielectrically Isolated (DifetTM) Amps-Difet processing enables design extremely input leakage
amplifiers eliminating substrate junction diode present junction isolated processes. This technique yields very high-precision, low-noise amps. Difet processes also minimize parasitic capacitance output transistor saturation effects, resulting improved bandwidth wider output swing.

High-Speed Amplifiers
develops high-speed signal conditioning products using state-ofthe-art processes that give leadingedge performance. Used high-speed signal chains analog-to-digital drive circuits, high-speed amps broadly defined amplifier having least 50MHz bandwidth least 100V/µs slew rate. High-speed amps from come several different types supply voltage options. primary benefit reducing even order harmonics, thereby reducing total harmonic distortion. also rejects common-mode components signal provides larger output swing load relative single-ended amplifiers. Fully differential amplifiers well-suited driving analog-to-digital converters. VCOM sets output common-mode voltage required newer, singlesupply, ADCs. FET-Input CMOS) amplifiers-have higher input impedance than typical bipolar amps more useful interfacing high impedance sources, such photodiodes transimpedance circuits. Video amplifiers-can used number different ways, generally signal path amplifying, buffering, filtering driving video lines. specifications most interest differential gain differential phase. Current-feedback amps typically used video applications, because their combination high slew rate excellent output drive quiescent power. Fixed variable gain-these amps have either fixed gain, variable gain that either digitally with control pins, linearly with control voltage. Fixed-gain amplifiers fixed internally with gain setting resistors. Variable gain amplifiers have different gain ranges, also differential input and/or output.
Design Considerations
Voltage-feedback type-the most commonly used basic building block most analog signal chains such gain blocks, filtering, level shifting, buffering, etc. Most voltage-feedback amps unity-gain stable, though some decompensated provide wider bandwidth, faster slew rate lower noise. Current-feedback type-most commonly seen video line driver applications, designs where extremely fast slew rate needed. Fully differential amplifier (FDA)-the fully differential input output topology
Packaging-high-speed amplifiers typically come surface-mount packages, because parasitics packages limit performance. Industry standard surface-mount packages (SOIC, MSOP, TSSOP QFN) handle highest speed requirements. bandwidths approaching 1GHz higher, package decreases inductance capacitance. Evaluation boards-high-speed amps have associated fully populated evaluation module (EVM) unpopulated printed circuit board (PCB). These boards very important part high-speed amplifier evaluation, since layout critical design success. make layout simple, Gerber files EVMs available. page more information.

These threechannel devices were first offer fully independent programmability functions each channel, which provides designer flexibility configure video system required on-the-fly, without need hardware upgrades modifications. devices designed with integrated Butterworth filters provide analog signal conditioning required video applications such set-top boxes, digital televisions, personal video recorders/DVD readers portable devices. These highlyintegrated devices provide space savings result high levels integration advanced package technology. strong combination integrated features optimized design make TI's THS7327 THS7347 well-suited projectors professional video systems. Both three-channel RGBHV video buffers offer monitor pass-through amplifier, unity gain buffer, input mux, control functions each channel, sync paths with Adjustable Schmitt Trigger, selectable bias modes rail-to-rail output that swings within 100mV rails allow either coupling. THS7347 incorporates 500MHz bandwidth, 1200V/µs unity-gain buffer making ideal driving ADCs video decoders, where THS7327 offers integrated fifth order Butterworth anti-aliasing filter each channel. These filters improve image quality eliminating images. standard definition (SDTV) THS7314 high definition (HDTV) THS7316 easily meet these trade-offs maintaining outstanding low-cost performance while EDTV/SDTV line driver THS7318, with small profile wafer chipscale package (WCSP), ideal board space-sensitive applications. power THS7374 THS7375 single-supply fourchannel fully-integrated video amplifiers that configured either dc-coupled inputs. 9.5MHz, they perfect choice SDTV video which includes composite (CVBS), S-Video, Y'U'V', G'B'R' (R'G'B'), component Y'P'BP'R 480i/576i signals SCART systems. Their rail-to-rail output swings within 100mV from rails supports driving lines channel allowing output coupling. Incorporating 6th-order Butterworth filter data converter image rejection, they also used reconstruction filter. THS7374 provides (2V/V) gain 6th-order Butterworth filter features 150MHz (-3dB) filter bypass mode. 9.6mA total quiescent current 3.3V operation makes THS7374 excellent choice powered other power sensitive video applications. THS7375 with 15dB (5.6V/V) gain makes ideal interface TI's DaVinciprocessors.
Video amplifiers-these devices
used number different ways, generally signal path amplifying, buffering, filtering driving video lines. specifications most interest composite video signals, CVBS, differential gain differential phase. other video signals, such Y'P'BP'R RGB, bandwidth (both small signal large signal), slew rate most importance. Noise accuracy also considered important some high-end applications. traditional Voltage-Feedback (VFB) amplifiers widely used because their ability configured almost situation. Many amplifiers have ability accept input signals going negative rail ground), allowing many single-supply systems. Additionally, many amplifiers offer rail-to-rail outputs featuring widest dynamic range possible small supplies. Traditional amplifiers (non-RRO) designed video offer ability have very high slew rates, wide bandwidths, noise, very good characteristics. Current-feedback amps commonly found high-end video applications because their combination high slew rate excellent output drive quiescent power.

There also demand these devices provide power consumption well increased functionality, such ability drive either while maintaining good video performance specifications. These specifications include crosstalk, fast settling, gain flatness, switching glitch along with differential gain differential phase. OPA875 OPA3875 single triple multiplexers along with OPA4872, multiplexer easily meet these requirements. Using patented input stage switching approach, switching glitch much improved over earlier solutions. This technique uses current steering input switch while maintaining overall closed-loop design.
Portable Video- successfully designing high-performance video system into low-voltage portable applications requires careful attention many small details. Portable applications impose very challenging technical requirements beyond those required typical video applications demand particular trade-offs performance, power consumption, printed circuit board space cost. dc-coupled solution with integrated gain, low-pass filter, level-shifter, shutdown solves these challenges while maintaining good video performance eliminates need large, expensive discrete components.

Line driver generic term that covers large subsets applications that typically require high bandwidth, large slew rate, high output current, combined with sufficient output voltage swing. load inductive, resistive, capacitive, circuit configuration vary from singleended fully differential. Once minimum requirement driving load adequate frequency with adequate distortion achieved, each individual end-application will have important specifications. These specifications generally include differential gain differential phase (for broadcast video line driver), quiescent power noise (for xDSL applications), load stability (for generators high load driver). wireline communications, latest introductions THS6204 xDSL market OPA2673 market. Although specified VDSL market, THS6204 used fully differential application that requires combination high slew rate, high bandwidth high output current. intended drive heavy loads (25) maintain large output swing. large slew rate (2600V/s) allows bandwidth maintained independently output voltage swing frequency. OPA2673 +12V high output current operational amplifier with active off-line control.
OPA2673 first amplifier combine active off-line control with current-feedback amplifier. active off-line control ensures that amplifier maintained into off-mode when large signal driven directly output, feature offered standard current-feedback architecture. This feature OPA2673 allows simplification control circuitry TDMA reduces both complexity cost system.

Difference Amplifiers
difference amplifier moderate input impedance, closed-loop, fixedgain block that allows acquisition signals presence ground loops noise. These devices used variety precision, generalpurpose, audio, low-power, high-speed high-common-mode voltage applications.
Should Difference Amplifier Instrumentation Amplifier?
Difference amplifiers excel when measuring signals with common-mode voltages greater than power supply rails, when there power requirement, when small package needed, when source impedance when low-cost differential required. difference building block instrumentation amp. Instrumentation amplifiers designed amplify low-level differential signals where maximum common-mode voltage within supply rails. Generally, using adjustable gain block, they well-suited single-supply applications. three-op-amp topology works well down Gain with performance advantage CMR. two-op-amp topology appropriate tasks requiring small package footprint gain greater. best choice low-voltage, single-supply applications.
Difference Amplifier
basic difference amplifier employs four on-chip, precision, laser trimmed resistors. INA132, example, operates 2.7V supplies consumes only 160µA. differential gain high common-mode rejection. output signal offset applying voltage pin. output sense connected directly load reduce gain error. Because resistor network divides down input voltages, difference amplifiers operate with input signals that exceed power supplies.
Output voltage swing-lower supply voltage often drives need maximize dynamic range swinging close rails. Common-mode input voltage range- selection most suitable difference begins with understanding input voltage range. Some offer resistor networks that divide down input voltages, allowing operation with input signals that exceed power supplies. five-resistor version simple difference amplifier results device that operate with very high levels common-mode voltage-far beyond supply rails. Gain-signal amplification needed desired circuit function must considered. With uncommitted on-chip amp, INA145 INA146 configured gains 1000. Sensor impedance-should <0.001 difference input impedance retain gain accuracy. other words, input impedance should 1,000 times higher than source impedance.
Offset voltage drift (µV/°C)-input offset voltage changes over temperature. This more critical applications with changing ambient temperature. Quiescent current-often high importance battery-powered applications, where amplifier power consumption greatly influence battery life. Slew rate-if signal reporting temperature, force pressure, slew rate generally great concern. signal electronic event, (e.g., current, power output) fast transition needed. Common-mode rejection-a measure unwanted signal rejection amp's ability extract signal from surrounding power line other electrical noise.
High Common-Mode Voltage Difference Amplifier Topology
five-resistor version simple difference amplifier results device that operate with very high levels common-mode voltage-far beyond power supply rails. example, INA117 sense differential signals presence common-mode voltages high ±200V while being powered from ±15V. This device very useful measuring current from high-voltage power supply through high-side shunt resistor.
Design Considerations
Power supply-common-mode voltage always function supply voltage. INA103 instrumentation amplifier designed operate voltage supplies ±25V, while INA122 difference operated from 2.2V supply.

Symmetrical inverting non-inverting gain paths provide better commonmode rejection high frequencies. Some types current-feedback-type input amps which maintain excellent bandwidth high gain.
rail-to-rail instrumentation amps suitable wide variety applications requiring maximum dynamic signal range. Gain requirement-for high-gain applications consider total noise device, because drift, input bias current voltage offset contribute error. Common-mode voltage range-the voltage input range over which amplifier operate differential pair behaves linear amplifier differential signals. Input bias current-can important factor many applications, especially those sensing current where sensor impedance very high. INA116 requires only typical input bias current. Offset voltage drift-IAs generally used high-gain applications, where errors amplified circuit gain. These errors become significant unless drift performance considered device selection. Bipolar input stage INAs generally have smaller error contribution from offset drift source inpedance applications.
