# GN358D

**GN Semic** · Operational Amplifier · SOP-8

GN358D from GN Semic, 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 | 1OUT | output | Output of operational amplifier 1. |
| 2 | 1IN- | input | Inverting input of operational amplifier 1. |
| 3 | 1IN+ | input | Non-inverting input of operational amplifier 1. |
| 4 | GND | power_in | Ground reference pin for the device. |
| 5 | 2IN+ | input | Non-inverting input of operational amplifier 2. |
| 6 | 2IN- | input | Inverting input of operational amplifier 2. |
| 7 | 2OUT | output | Output of operational amplifier 2. |
| 8 | Vcc | power_in | Positive supply voltage: single supply 4 to 24 V, or dual supply ±2 to ±12 V, per the datasheet ratings on page 2. |

## CAD (KiCad official)

- Symbol: `GN358D`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOP-8 (KiCad packages3D, STEP)
- 3D model files: `gn358d-etched.step` / `gn358d-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `gn358d.step` / `gn358d.glb` are the bare package body.
