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, typically swings to within 8mV of the supply rails into >1kΩ loads and 30mV into 150Ω loads. Sources/sinks up to 80mA (min 60mA). |+| 2 | INA- | input | Amplifier A inverting input. High-impedance CMOS input (typical bias current 1pA). Common-mode voltage range: -0.2V to +3.8V (relative to Vss on a 5V supply). |+| 3 | INA+ | input | Amplifier A non-inverting input. High-impedance CMOS input (typical bias current 1pA). Must remain within Vss-0.5V to VDD+0.5V absolute maximum. |+| 4 | VSS | power_in | Negative supply / ground. Tie to GND for single-supply operation, or to -1.25V to -2.75V for dual-supply operation. Bypass to ground with a 0.1µF ceramic close to the pin (dual-supply case). |+| 5 | INB+ | input | Amplifier B non-inverting input. High-impedance CMOS input (typical bias current 1pA). Must remain within Vss-0.5V to VDD+0.5V absolute maximum. |+| 6 | INB- | input | Amplifier B inverting input. High-impedance CMOS input (typical bias current 1pA). Common-mode voltage range: -0.2V to +3.8V (relative to Vss on a 5V supply). |+| 7 | OUTB | output | Amplifier B output. Rail-to-rail output, typically swings to within 8mV of the supply rails into >1kΩ loads and 30mV into 150Ω loads. Sources/sinks up to 80mA (min 60mA). |+| 8 | VDD | power_in | Positive supply. +2.5V to +5.5V single-supply operating range (absolute max +7.5V referenced to VSS). Bypass to ground with a 0.1µF ceramic capacitor close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Gainsil |+| Package | SOP-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `GS8052-SRSR`+- `GS8052-SRMR`+- `GS8052-SRFR`++## CAD (KiCad official)++- Symbol: `GS8052-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/gs8052-sr-datasheet.pdf) (22 pp, sha256 `ca76cde4b640e8a0`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
