OPA189ID 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; can be left floating |
| 2 | -IN | input | Inverting input accepting common-mode voltage from (V-) - 0.5 to (V+) + 0.5 V and input current up to ±10 mA |
| 3 | +IN | input | Noninverting input accepting common-mode voltage from (V-) - 0.5 to (V+) + 0.5 V and input current up to ±10 mA |
| 4 | V- | power_in | Negative power supply with recommended operating voltage from 4.5 V to 36 V single-supply or ±2.25 V to ±18 V dual-supply |
| 5 | NC | unconnected | No internal connection; can be left floating |
| 6 | OUT | output | Output providing rail-to-rail operation from V- to V+ |
| 7 | V+ | power_in | Positive power supply with recommended operating voltage from 4.5 V to 36 V single-supply or ±2.25 V to ±18 V dual-supply |
| 8 | NC | unconnected | No internal connection; can be left floating |
