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 | OUTPUT(1) | output | Amplifier 1 speaker/headphone output. AC-couple to load via an output DC-blocking capacitor (e.g. 100-470 µF) with a Zobel network (0.1 µF + 4.7 Ω) to ground for stability. Peak output current 1 A. |+| 2 | VS | power_in | Positive supply voltage (VS). Recommended operating range 1.8 V to 15 V (absolute max 15 V). Bypass to GND with a 10 µF electrolytic close to the pin. |+| 3 | OUTPUT(2) | output | Amplifier 2 speaker/headphone output. AC-couple to load via an output DC-blocking capacitor with a Zobel network (0.1 µF + 4.7 Ω) to ground for stability. Peak output current 1 A. |+| 4 | GND | power_in | Device ground / power return for both amplifier channels. Connect to system ground with a low-impedance path. |+| 5 | INPUT-(2) | input | Amplifier 2 inverting input. Typically bypassed to GND via a large electrolytic (e.g. 100 µF) to set unity feedback for the internally-fixed gain (~39 dB closed-loop) and reject DC. Input bias current up to 100 nA. |+| 6 | INPUT+(2) | input | Amplifier 2 non-inverting input (right channel in stereo mode). AC-couple the audio source; a ~10 kΩ resistor to GND sets the input DC bias. Input resistance typ. 100 kΩ. |+| 7 | INPUT+(1) | input | Amplifier 1 non-inverting input (left channel in stereo mode). AC-couple the audio source; a ~10 kΩ resistor to GND sets the input DC bias. Input resistance typ. 100 kΩ. |+| 8 | INPUT-(1) | input | Amplifier 1 inverting input. Typically bypassed to GND via a large electrolytic (e.g. 100 µF) to set unity feedback for the internally-fixed gain (~39 dB closed-loop) and reject DC. Input bias current up to 100 nA. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | STMicroelectronics |+| Package | SOIC-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `TDA2822D013TR`++## CAD (KiCad official)++- Symbol: `TDA2822D013TR`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [STMicroelectronics datasheet](https://www.st.com/resource/en/datasheet/tda2822d013tr.pdf) (12 pp, sha256 `d75f4b0043b686bd`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
