# GC2822Z

**Gcore** · Audio Power OpAmps · DIP-8

GC2822Z from Gcore, in a DIP-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 | 1OUT | output | Channel 1 audio power output. Drives the speaker/headphone load (typ. 4-32 ohm) through an output coupling capacitor in stereo mode, or directly as one leg of the BTL pair in bridge mode. Output current rated up to 0.6 A absolute maximum. |
| 2 | Vcc | power_in | Positive supply pin. Operating range 3 V to 12 V (absolute max 15 V). Bypass with a bulk capacitor (typ. 100 uF) plus a 0.1 uF ceramic to ground. |
| 3 | 2OUT | output | Channel 2 audio power output. Drives the speaker/headphone load through an output coupling capacitor in stereo mode, or acts as the second BTL output in bridge mode. |
| 4 | GND | power_in | Ground / 0 V reference for the device. |
| 5 | 2IN- | input | Channel 2 inverting input. Used for the feedback network setting the closed-loop voltage gain (typ. 40 dB) via an RC network to ground. |
| 6 | 2IN+ | input | Channel 2 non-inverting input. Audio signal enters here through an AC-coupling capacitor; input impedance typ. >=100 kohm. |
| 7 | 1IN+ | input | Channel 1 non-inverting input. Audio signal enters here through an AC-coupling capacitor; input impedance typ. >=100 kohm. |
| 8 | 1IN- | input | Channel 1 inverting input. Used for the feedback network setting the closed-loop voltage gain (typ. 40 dB) via an RC network to ground. |

## CAD (KiCad official)

- Symbol: `GC2822Z`
- Footprint: `Package_DIP:DIP-8_W7.62mm`
- 3D model: DIP-8 (KiCad packages3D, STEP)
- 3D model files: `gc2822z-etched.step` / `gc2822z-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `gc2822z.step` / `gc2822z.glb` are the bare package body.
