# GN07C

**GN Semic** · Precision OpAmps · SOP-8

GN07C from GN Semic, 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 | VOS_TRIM1 | passive | External offset-voltage trim terminal 1 (Offset Null). Connect to the wiper of a 20kΩ potentiometer with the ends tied to pin 8 and the pot returned to V+ (Vcc) to null input offset voltage. |
| 2 | IN- | input | Inverting input of the op-amp. Common-mode input range ±13V typical, input bias current ~28nA, input offset current ~8nA max. |
| 3 | IN+ | input | Non-inverting input of the op-amp. Common-mode input range ±13V typical, input bias current ~28nA. |
| 4 | V- | power_in | Negative supply rail (Vee). Dual supply operation −3V to −20V; single-supply operation with V+ = 6..40V referenced to this pin as ground. |
| 5 | NC | unconnected | No-connect. Leave floating; do not tie to any signal or supply. |
| 6 | OUT | output | Op-amp output. Peak output swing ±12V into 10kΩ, ±11.5V into 2kΩ; gain-bandwidth product 0.5MHz typical. |
| 7 | V+ | power_in | Positive supply rail (Vcc). Dual supply +3V to +20V; single-supply 6..40V total across V+ and V−. Typical quiescent current ~3.8mA. |
| 8 | VOS_TRIM2 | passive | External offset-voltage trim terminal 2 (Offset Null). Used with pin 1 across a 20kΩ potentiometer, wiper to V+, to null input offset voltage. |

## CAD (KiCad official)

- Symbol: `GN07C`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOP-8 (KiCad packages3D, STEP)
- 3D model files: `gn07c-etched.step` / `gn07c-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `gn07c.step` / `gn07c.glb` are the bare package body.

## 3D model downloads

Two STEP files. Same geometry, different body top:

| File | Size | Use it when |
|---|---|---|
| [`gn07c.step`](gn07c.step) | 122 KB | You want the bare part, or you mark your own boards. |
| [`gn07c-etched.step`](gn07c-etched.step) | 1.2 MB | You want the part with `GN07C` already on it. |

The marking in the etched file is real recessed geometry cut into the solid, not a
texture or a decal: 312 faces against 147 in the bare model. It
survives export, section views, and rendering in any CAD tool, and it drops straight
into KiCad or Fusion with no extra setup.
