APPLICATIONS INFORMATION
OPA353 series amps fabricated state-of-the-art micron CMOS process. They unity-gain stable suitable wide range general purpose applications. Rail-to-rail input/output make them ideal driving sampling converters. They well suited controlling output power cell phones. These applications often require high speed noise. addition, OPA353 series offers cost solution general purpose consumer video applications drive capability). Excellent performance makes OPA353 series well suited audio applications. Their bandwidth, slew rate, noise (5nV/Hz), (0.0006%), small package options ideal these applications. class output stage capable driving loads connected point between ground. Rail-to-rail input output swing significantly increases dynamic range, especially voltage supply applications. Figure shows input output waveforms
OPA353 unity-gain configuration. Operation from single supply with load connected input 5Vp-p sinusoid. Output voltage approximately 4.95Vp-p. Power supply pins should bypassed with 0.01µF ceramic capacitors. OPERATING VOLTAGE OPA353 series amps fully specified from +2.7V +5.5V. However, supply voltage range from +2.5V +5.5V. Parameters guaranteed over specified supply range-a unique feature OPA353 series. addition, many specifications apply from -40°C +85°C. Most behavior remains virtually unchanged throughout full operating voltage range. Parameters which vary significantly with operating voltages temperature shown typical performance curves. RAIL-TO-RAIL INPUT guaranteed input common-mode voltage range OPA353 series extends 100mV beyond supply rails. This achieved with complementary input stage-an N-channel input differential pair parallel with P-channel differential pair (see Figure N-channel pair active input voltages close positive rail, typically (V+) 1.8V 100mV above positive supply, while P-channel pair inputs from 100mV below negative supply approximately (V+) 1.8V. There small transition region, typically (V+) (V+) 1.6V, which both pairs This 400mV transition region vary ±400mV with process variation. Thus, transition region (both input stages range from (V+) 2.4V (V+) 2.0V end, (V+) 1.6V (V+) 1.2V high end.

double-folded cascode adds signal from input pairs presents differential signal class output stage. Normally, input bias current approximately 500fA. However, large inputs (greater than 300mV beyond supply rails) turn OPA353's input protection diodes, causing excessive current flow input pins. Momentary voltages greater than 300mV beyond power supply tolerated current input pins limited 10mA. This easily accomplished with input resistor shown Figure Many input signals inherently current-limited less than 10mA, therefore, limiting resistor required.
FEEDBACK CAPACITOR IMPROVES RESPONSE optimum settling time stability with high-impedance feedback networks, necessary feedback capacitor across feedback resistor, shown Figure This capacitor compensates zero created feedback network impedance OPA353's input capacitance (and parasitic layout capacitance). effect becomes more significant with higher impedance networks.

FIGURE Input Current Protection Voltages Exceeding Supply Voltage. RAIL-TO-RAIL OUTPUT class output stage with common-source transistors used achieve rail-to-rail output. light resistive loads (>10k), output voltage swing typically millivolts from supply rails. With heavier resistive loads (600 10k), output swing within tens millivolts from supply rails maintain high open-loop gain. typical performance curves "Output Voltage Swing Output Current" "Open-Loop Gain Output Voltage." CAPACITIVE LOAD STABILITY OPA353 series amps drive wide range capacitive loads. However, amps under certain conditions become unstable. configuration, gain, load value just factors consider when determining stability. unity gain configuration most susceptible effects capacitive load. capacitive load reacts with amp's output impedance, along with additional load resistance, create pole small-signal response which degrades phase margin. unity gain, OPA353 series amps perform well with large capacitive loads. Increasing gain enhances amplifier's ability drive more capacitance. typical performance curve "Small-Signal Overshoot Capacitive Load" shows performance with resistive load. Increasing load resistance improves capacitive load drive capability.

DRIVING CONVERTERS OPA353 series amps optimized driving medium speed 500kHz) sampling converters. However, they also offer excellent performance higher speed converters. OPA353 series provides effective means buffering A/D's input capacitance resulting charge injection while providing signal gain. applications requiring high accuracy, OPA350 series recommended.

When used with miniature package options OPA353 series, combination ideal space-limited power applications. further information consult ADS7861 data sheet. OUTPUT IMPEDANCE frequency open-loop output impedance OPA353's common-source output stage approximately When connected with feedback, this value reduced significantly loop gain amp. example, with 122dB open-loop gain, output impedance reduced unity-gain less than 0.001. each decade rise closed-loop gain, loop gain reduced same amount which results ten-fold increase output impedance (see typical performance curve, "Output Impedance Frequency"). higher frequencies, output impedance will rise open-loop gain drops. However, these frequencies output also becomes capacitive parasitic capacitance. This prevents output impedance
from becoming high, which cause stability problems when driving capacitive loads. mentioned previously, OPA353 excellent capacitive load drive capability with bandwidth.
