OPA211IDR 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 or connected to any voltage between (V-) and (V+). |
| 2 | -IN | input | Inverting input. |
| 3 | +IN | input | Noninverting input. |
| 4 | V- | power_in | Negative power supply. |
| 5 | NC | unconnected | No internal connection; can be left floating or connected to any voltage between (V-) and (V+). |
| 6 | OUT | output | Output. |
| 7 | V+ | power_in | Positive power supply. |
| 8 | Shutdown | input | Shutdown control, active high; device enabled when (V-) ≤ VSHUTDOWN ≤ (V+) - 3 V and disabled when VSHUTDOWN ≥ (V+) - 0.35 V. |
