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. |
