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; typical short-circuit limit 60mA, output current 65mA. |+| 2 | INA- | input | Amplifier A inverting input. Rail-to-rail input range extending from VSS-0.1V to VDD+0.1V; typical input bias current 20pA. |+| 3 | INA+ | input | Amplifier A non-inverting input. Rail-to-rail input range extending from VSS-0.1V to VDD+0.1V; typical input bias current 20pA. |+| 4 | VSS | power_in | Negative supply / ground. Single-supply operation ties this to GND; dual-supply operation uses ±0.9V to ±2.75V. Bypass with 0.1µF to ground. |+| 5 | INB+ | input | Amplifier B non-inverting input. Rail-to-rail input range extending from VSS-0.1V to VDD+0.1V; typical input bias current 20pA. |+| 6 | INB- | input | Amplifier B inverting input. Rail-to-rail input range extending from VSS-0.1V to VDD+0.1V; typical input bias current 20pA. |+| 7 | OUTB | output | Amplifier B output. Rail-to-rail output stage; typical short-circuit limit 60mA, output current 65mA. |+| 8 | VDD | power_in | Positive supply. Single-supply range 1.8V to 5.5V (absolute max 7.5V VDD-to-VSS). Bypass with 0.1µF ceramic close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Gainsil |+| Package | SOP-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `GS6552-SR`+- `GS6552-SRGS6552-MR`++## CAD (KiCad official)++- Symbol: `GS6552-SR`+- 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:** [Gainsil datasheet](docs/gs6552-sr-datasheet.pdf) (14 pp, sha256 `55a4bcd77e36ce38`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
