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. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Gcore |+| Package | DIP-8 |+| Category | Operational Amplifier/Comparator |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `GC2822ZZ`++## CAD (KiCad official)++- Symbol: `GC2822Z`+- Footprint: `Package_DIP:DIP-8_W7.62mm`+- 3D model: DIP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Gcore datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8590400618268692480) (5 pp, sha256 `163a984d97eaed25`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
