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 swing; can source/sink typically 53mA (min 35mA over full temp range). Closed-loop output impedance ~3 ohm at 200kHz, G=1. |+| 2 | INA- | input | Amplifier A inverting input. Rail-to-rail input; allowable analog input range Vss-0.5V to Vdd+0.5V (absolute max). Input bias current typ 1pA. |+| 3 | INA+ | input | Amplifier A non-inverting input. Rail-to-rail input; common-mode range includes ground (-0.1V to Vdd+0.1V typ at Vs=5.5V). Input bias current typ 1pA. |+| 4 | VSS | power_in | Negative supply / ground. Single-supply operation: connect to 0V (GND) with VDD at +2.1V to +5.5V. Absolute max VDD-VSS = 7.5V. |+| 5 | INB+ | input | Amplifier B non-inverting input. Rail-to-rail input with the same characteristics as amplifier A's non-inverting input. |+| 6 | INB- | input | Amplifier B inverting input. Rail-to-rail input with the same characteristics as amplifier A's inverting input. |+| 7 | OUTB | output | Amplifier B output. Rail-to-rail output with the same drive characteristics as OUTA. |+| 8 | VDD | power_in | Positive supply. Operating range +2.1V to +5.5V (absolute max +7.5V referred to VSS). PSRR typ 91dB at Vs=2.5V to 5.5V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Gainsil |+| Package | SOP-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `GS8632-SRSR`+- `GS8632-SRMR`++## CAD (KiCad official)++- Symbol: `GS8632-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/gs8632-sr-datasheet.pdf) (19 pp, sha256 `c17e6fe6cae0310b`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
