OPA2322AIDR from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT A | output | Channel A amplifier output; rail-to-rail swing within 10 mV typ / 20 mV max of each supply rail at RL = 10 kΩ; short-circuit current ±65 mA at VS = 5.5 V. |
| 2 | -IN A | input | Channel A inverting input; common-mode range (V-) - 0.1 V to (V+) + 0.1 V; input bias current ±0.2 pA typ / ±10 pA max; current-limit to 10 mA if signal can swing >0.5 V beyond supply rails. |
| 3 | +IN A | input | Channel A non-inverting input; common-mode range (V-) - 0.1 V to (V+) + 0.1 V; input bias current ±0.2 pA typ / ±10 pA max; current-limit to 10 mA if signal can swing >0.5 V beyond supply rails. |
| 4 | V- | power_in | Negative power supply; single-supply range 1.8 V to 5.5 V or split-supply ±0.9 V to ±2.75 V; bypass to V+ with 0.001 µF to 0.1 µF ceramic capacitor placed as close to the device as possible. |
| 5 | +IN B | input | Channel B non-inverting input; common-mode range (V-) - 0.1 V to (V+) + 0.1 V; input bias current ±0.2 pA typ / ±10 pA max; current-limit to 10 mA if signal can swing >0.5 V beyond supply rails. |
| 6 | -IN B | input | Channel B inverting input; common-mode range (V-) - 0.1 V to (V+) + 0.1 V; input bias current ±0.2 pA typ / ±10 pA max; current-limit to 10 mA if signal can swing >0.5 V beyond supply rails. |
| 7 | OUT B | output | Channel B amplifier output; rail-to-rail swing within 10 mV typ / 20 mV max of each supply rail at RL = 10 kΩ; short-circuit current ±65 mA at VS = 5.5 V. |
| 8 | V+ | power_in | Positive power supply; single-supply range 1.8 V to 5.5 V; quiescent current 1.5 mA typ / 1.75 mA max per channel at VS = +5.5 V; bypass to V- with 0.001 µF to 0.1 µF ceramic capacitor placed as close to the device as possible. |
