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 | OUTA | output | Amplifier A output. Rail-to-rail output stage; can swing within a few mV of VSS/VDD under light load (>100 kΩ) and within ~60 mV at 10 kΩ. Short-circuit current ~60 mA. |+| 2 | INA- | input | Amplifier A inverting input. Rail-to-rail common-mode range from VSS-0.1 V to VDD+0.1 V. Input bias current 20 pA (typ). |+| 3 | INA+ | input | Amplifier A non-inverting input. Rail-to-rail common-mode range from VSS-0.1 V to VDD+0.1 V. Input bias current 20 pA (typ). |+| 4 | VSS | power_in | Negative supply / ground. In single-supply mode connect to GND; in dual-supply mode connect to the negative rail. Total supply (VDD-VSS) range 1.8 V to 5.5 V (7.5 V abs max). |+| 5 | INB+ | input | Amplifier B non-inverting input. Rail-to-rail common-mode range from VSS-0.1 V to VDD+0.1 V. Input bias current 20 pA (typ). |+| 6 | INB- | input | Amplifier B inverting input. Rail-to-rail common-mode range from VSS-0.1 V to VDD+0.1 V. Input bias current 20 pA (typ). |+| 7 | OUTB | output | Amplifier B output. Rail-to-rail output stage; can swing within a few mV of VSS/VDD under light load (>100 kΩ) and within ~60 mV at 10 kΩ. Short-circuit current ~60 mA. |+| 8 | VDD | power_in | Positive supply. Single-supply 1.8 V to 5.5 V (7.5 V abs max). Bypass with a 0.1 µF ceramic to VSS/GND close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Gainsil |+| Package | SOIC-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `GS8552-SR`+- `GS8552-SRGS8552-MR`++## CAD (KiCad official)++- Symbol: `GS8552-SR`+- 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:** [Gainsil datasheet](docs/gs8552-sr-datasheet.pdf) (14 pp, sha256 `dc9b0f2b6cedff03`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
