# OP07DM

**HGSEMI** · Operational Amplifier · SOP-8

OP07DM from HGSEMI, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Offset Null 1 | passive | Input offset voltage nulling terminal 1. Connect a 20kΩ potentiometer between pins 1 and 8, with the wiper tied to V_CC+ to trim residual input offset voltage to zero. |
| 2 | Inverting Input | input | Inverting (-) analog input of the op-amp. Differential input voltage rating ±30V, common-mode range typically ±13.5V; differential input resistance 33MΩ. |
| 3 | Non-inverting Input | input | Non-inverting (+) analog input of the op-amp. Differential input voltage rating ±30V, common-mode range typically ±13.5V; differential input resistance 33MΩ. |
| 4 | VCC- | power_in | Negative supply rail. Operating range ±3V to ±16V (i.e. -3V to -16V referenced to VCC+). Typical no-load supply current 2.7mA (5mA max). |
| 5 | N.C. | unconnected | No internal connection. Leave floating or optionally tie to a stable potential; do not use as a routing via. |
| 6 | Output | output | Op-amp output. Swings typically ±13V into 10kΩ and ±12.8V into 2kΩ; open-loop output resistance 60Ω; slew rate 0.17V/µs; gain-bandwidth product 0.5MHz. |
| 7 | VCC+ | power_in | Positive supply rail. Operating range ±3V to ±16V; also serves as the wiper reference for the external offset-null potentiometer connected between pins 1 and 8. |
| 8 | Offset Null 2 | passive | Input offset voltage nulling terminal 2. Connect a 20kΩ potentiometer between pins 1 and 8, with the wiper tied to V_CC+ to null residual input offset voltage. |
