OPA2322AIDRGR from Texas Instruments, in a WSON-8-EP(3x3). 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, with continuous short-circuit to ground allowed for one amplifier per package. |
| 2 | -IN A | input | Channel A inverting input, diode-clamped to the supply rails, with input current limited to 10 mA if signals swing more than 0.5 V beyond the rails. |
| 3 | +IN A | input | Channel A noninverting input, diode-clamped to the supply rails, with input current limited to 10 mA if signals swing more than 0.5 V beyond the rails. |
| 4 | V- | power_in | Negative supply, 0 V in single-supply use or down to ±0.9 V to ±2.75 V split supply. |
| 5 | +IN B | input | Channel B noninverting input, diode-clamped to the supply rails, with input current limited to 10 mA if signals swing more than 0.5 V beyond the rails. |
| 6 | -IN B | input | Channel B inverting input, diode-clamped to the supply rails, with input current limited to 10 mA if signals swing more than 0.5 V beyond the rails. |
| 7 | OUT B | output | Channel B amplifier output, rail-to-rail. |
| 8 | V+ | power_in | Positive supply, 1.8 V to 5.5 V single supply (6 V absolute maximum), with local 0.001 µF to 0.1 µF ceramic bypass recommended. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
