OPA322AIDBVR

Texas Instruments · Operational Amplifier · SOT-23-5

OPA322AIDBVR from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUT output Amplifier output. Rail-to-rail output swing to within ~10 mV of either supply rail with RL = 10 kΩ. Short-circuit current is typically ±65 mA at VS = 5.5 V; open-loop output resistance ~90 Ω at 1 MHz.
2 V- power_in Negative supply rail. Tie to GND for single-supply operation (1.8 V to 5.5 V total supply), or to a negative rail for split-supply operation (±0.9 V to ±2.75 V). Bypass with a 0.1-µF ceramic capacitor to V+ as close to the device as possible.
3 +IN input Non-inverting input. Rail-to-rail common-mode range from (V-) - 0.1 V to (V+) + 0.1 V. Input bias current typically ±0.2 pA at 25°C; inputs are ESD-diode-clamped to the supplies (limit external overdrive current to ≤10 mA).
4 -IN input Inverting input. Same rail-to-rail common-mode range and ±0.2 pA typical bias current as the +IN pin. Used with the OUT pin to set closed-loop gain via an external feedback network.
5 V+ power_in Positive supply rail. Operating range 1.8 V to 5.5 V single-supply (or ±0.9 V to ±2.75 V split-supply); absolute maximum (V+) - (V-) = 6 V. Bypass with a 0.1-µF ceramic capacitor to V- close to the pin.
