OP177FM from HGSEMI, in a SOP-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 | VOS TRIM | passive | Offset null (input offset voltage trim) terminal, connected to one end of a 20kΩ trim potentiometer whose wiper goes to Vcc+. |
| 2 | -IN | input | Inverting input; absolute maximum input voltage ±18 V and differential input voltage ±30 V. |
| 3 | +IN | input | Non-inverting input; absolute maximum input voltage ±18 V and differential input voltage ±30 V. |
| 4 | V- | power_in | Negative supply; operating supply range ±3V to ±18V, absolute maximum ±18 V. |
| 5 | NC | unconnected | No connect; not internally connected. |
| 6 | OUT | output | Amplifier output; typical peak output swing ±12 V into 10kΩ and ±11.5 V into 2kΩ at Vcc=±15V. |
| 7 | V+ | power_in | Positive supply; operating supply range ±3V to ±18V, absolute maximum ±18 V. |
| 8 | VOS TRIM | passive | Offset null (input offset voltage trim) terminal, connected to the other end of the 20kΩ trim potentiometer whose wiper goes to Vcc+. |
