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 | SHUTDOWN | input | Shutdown control input. Drive high (near VDD) to place the amplifier in low-power shutdown mode (IQ ≈ 0.6µA). A pull-up resistor is recommended when driven by a switch to avoid indeterminate intermediate levels. |+| 2 | BYPASS | passive | Internal bias reference (VDD/2) bypass. Connect a 1µF capacitor to GND placed close to the IC to stabilize the internal mid-supply bias and improve PSRR. Larger CB values further improve PSRR. |+| 3 | +IN | input | Non-inverting audio input to the first internal op-amp. Typically referenced to the BYPASS node in single-ended input applications. |+| 4 | -IN | input | Inverting audio input to the first internal op-amp. Combined with Rf and Ri sets closed-loop gain AVD = 2 × (Rf/Ri); typical Rf = Ri = 20kΩ for AVD = 2. |+| 5 | VO1 | output | Bridge-tied-load audio output 1 (first op-amp output). Connect one side of the speaker (typ. 4Ω or 8Ω) between VO1 and VO2; no output DC blocking capacitor is required. |+| 6 | VDD | power_in | Positive supply input, 2.0V to 5.0V (absolute max 5.5V). Bypass with a 1µF tantalum (Cs) to GND close to the pin. |+| 7 | GND | power_in | Ground / 0V reference for the amplifier and bias network. |+| 8 | VO2 | output | Bridge-tied-load audio output 2 (second op-amp output, fixed gain AV = -1, inverted with respect to VO1). Connect the other side of the speaker between VO2 and VO1. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Shenzhen Fuman |+| Package | SOP-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## CAD (KiCad official)++- Symbol: `SC8002B`+- 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:** [Shenzhen Fuman datasheet](docs/sc8002b-datasheet.pdf) (6 pp, sha256 `5e481ab2fb5cf65b`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
