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 | SD | input | Shutdown control. High-level places the chip in shutdown/sleep mode (leakage ~18µA typ); low-level enables normal operation. Has an internal pull-up per the typical application diagram. |+| 2 | BYP | passive | Internal common-mode voltage (VDD/2) bypass. Connect a 1µF capacitor from this pin to GND to filter the mid-rail bias reference. |+| 3 | +IN | input | Non-inverting analog audio input to the internal input amplifier. |+| 4 | -IN | input | Inverting analog audio input. Gain is set by an external input resistor (e.g. 22kΩ) and feedback resistor (e.g. 68kΩ) as shown in the typical application. |+| 5 | VO1 | output | Bridge-tied load audio output 1. Connect one terminal of the speaker between VO1 (pin 5) and VO2 (pin 8). No output coupling capacitor required. |+| 6 | VCC | power_in | Positive supply voltage input, 2.2V to 5.5V operating range. Bypass locally with a 1µF (and typically an additional bulk) capacitor to GND. |+| 7 | GND | power_in | Power ground return for supply and audio output stage. |+| 8 | VO2 | output | Bridge-tied load audio output 2. Complementary to VO1; the speaker connects across VO1 and VO2 for full BTL drive. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | IDCHIP |+| Package | SOP-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `AD8002D`++## CAD (KiCad official)++- Symbol: `AD8002D`+- 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:** [IDCHIP datasheet](docs/ad8002d-datasheet.pdf) (4 pp, sha256 `5e0f72e6f3f7ec0e`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
