OPA381AIDGKT from Texas Instruments, in a VSSOP-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 | NC | unconnected | No internal connection. |
| 2 | V+ | power_in | Positive power supply; specified range 2.7V to 5.5V. |
| 3 | Out | output | Transimpedance amplifier output, linear operation 0.05V to (V+) − 0.6V with RL = 10kΩ load. |
| 4 | NC | unconnected | No internal connection. |
| 5 | V− | power_in | Negative power supply (ground for single-supply or −5V for extended output swing to 0V). |
| 6 | +In | input | Non-inverting input; common-mode voltage range V− to (V+) − 1.8V; used as fixed biasing point for photodiode reverse bias. |
| 7 | −In | input | Inverting input; common-mode voltage range V− to (V+) − 1.8V; connected to photodiode and feedback resistor. |
| 8 | NC | unconnected | No internal connection. |
