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 amplifier output. Drives speaker/headphone load (typ. 32 Ω / 16 Ω / 8 Ω); peak output current up to 0.8 A. AC-couple to load via output capacitor in single-ended mode. |+| 2 | Vcc | power_in | Positive supply voltage. Operating range 1.8 V to 7.5 V (absolute max 9.0 V). Typical 3-6 V; bypass with 10 µF electrolytic + 0.1 µF ceramic near the pin. |+| 3 | 2OUT | output | Channel 2 audio power amplifier output. Drives speaker/headphone load; peak output current up to 0.8 A. In BTL bridge mode this pin is the anti-phase output relative to pin 1. |+| 4 | GND | power_in | Ground / 0 V reference for the amplifier and internal bias circuit. |+| 5 | 2IN- | input | Channel 2 inverting input. Typically bypassed to ground through a 100 µF electrolytic (sets closed-loop gain of ~40 dB with internal feedback). Input impedance ≥ 100 kΩ. |+| 6 | 2IN+ | input | Channel 2 non-inverting input. Audio signal input (AC-coupled through source impedance / 10 kΩ bias resistor). In BTL bridge mode this pin is tied to ground while pin 7 receives the signal. |+| 7 | 1IN+ | input | Channel 1 non-inverting input. Audio signal input; source typically fed through a 10 kΩ bias/pull-down resistor to ground. |+| 8 | 1IN- | input | Channel 1 inverting input. Typically bypassed to ground with a 100 µF electrolytic to set the AC gain. In BTL bridge mode this pin is fed from the output of the other channel to invert its signal. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Silicore |+| Package | SOP-8 |+| Category | Operational Amplifier/Comparator |+| Pins | 8 |++## CAD (KiCad official)++- Symbol: `D2822M SOP8`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Silicore datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8588944786006396929) (6 pp, sha256 `4d9229b29f27061b`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
