OP37GM 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 (VOS trim) terminal, connected with pin 8 across a 20 kΩ potentiometer whose wiper goes to VCC+ to null the input offset voltage. |
| 2 | -IN | input | Inverting input; input voltage range is ±13 V typical with a maximum rating of ±18 V and differential input voltage up to ±30 V. |
| 3 | +IN | input | Non-inverting input; input voltage range is ±13 V typical with a maximum rating of ±18 V and differential input voltage up to ±30 V. |
| 4 | V- | power_in | Negative supply terminal; the device operates from supplies of ±3 V to ±18 V. |
| 5 | NC | unconnected | No connect; the datasheet marks this pin as NC = NO CONNECT. |
| 6 | OUT | output | Amplifier output; peak swing is ±12 V into 10 kΩ and ±11.5 V into 2 kΩ at VCC=±15 V. |
| 7 | V+ | power_in | Positive supply terminal; the device operates from supplies of ±3 V to ±18 V. |
| 8 | VOS TRIM | passive | Offset null (VOS trim) terminal, connected with pin 1 across a 20 kΩ potentiometer whose wiper goes to VCC+ to null the input offset voltage. |
