# OP07CSZ

**UMW** · Precision Op Amps · SOP-8

OP07CSZ from UMW, 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 (Offset Null 2) terminal connected to one end of a 20kΩ trim potentiometer whose wiper goes to VCC+ for input offset zeroing. |
| 2 | -IN | input | Inverting input of the amplifier, with input voltage range of ±13V typical and absolute maximum input voltage of ±18V. |
| 3 | +IN | input | Non-inverting input of the amplifier, with input voltage range of ±13V typical and absolute maximum input voltage of ±18V. |
| 4 | V- | power_in | Negative power supply (VCC-); supply range is ±3V to ±20V. |
| 5 | NC | unconnected | No connect; not internally connected. |
| 6 | OUT | output | Amplifier output, with peak output swing of ±12V typ at RL=2kΩ and ±13.5V typ at RL=10kΩ per the electrical characteristics table. |
| 7 | V+ | power_in | Positive power supply (VCC+); supply range is ±3V to ±20V and the trim potentiometer wiper connects here. |
| 8 | VOS TRIM | passive | Offset null (Offset Null 1) terminal connected to the other end of the 20kΩ trim potentiometer for input offset zeroing. |
