OPA188AID 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 | NC | unconnected | No internal connection; leave floating or ground. |
| 2 | -IN | input | Inverting input with common-mode range V- to (V+)−1.5V. |
| 3 | +IN | input | Non-inverting input with common-mode range V- to (V+)−1.5V. |
| 4 | V- | power_in | Negative power supply; recommended operating range ±2V to ±18V dual supply or 4V to 36V single supply. |
| 5 | NC | unconnected | No internal connection; leave floating or ground. |
| 6 | OUT | output | Output with rail-to-rail swing within 6mV to 350mV depending on load and temperature. |
| 7 | V+ | power_in | Positive power supply; recommended operating range ±2V to ±18V dual supply or 4V to 36V single supply. |
| 8 | NC | unconnected | No internal connection; leave floating or ground. |
