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; typically <5mV from either rail with RL >100kΩ, 30mV with 10kΩ. Sources/sinks up to ~60mA short-circuit current. |+| 2 | INA- | input | Amplifier A inverting input. Rail-to-rail common-mode range extending 100mV beyond the supplies (VSS-0.1V to VDD+0.1V). Input bias current 1pA typ. |+| 3 | INA+ | input | Amplifier A non-inverting input. Rail-to-rail common-mode range (VSS-0.1V to VDD+0.1V). Input bias current 1pA typ. |+| 4 | VSS | power_in | Negative supply / ground. Single-supply operation: connect to GND with VDD at 2.1V-5.5V. Dual-supply: ±1.05V to ±2.75V. Bypass with 0.1µF ceramic to ground if dual-supply. |+| 5 | INB+ | input | Amplifier B non-inverting input. Rail-to-rail common-mode range (VSS-0.1V to VDD+0.1V). Input bias current 1pA typ. |+| 6 | INB- | input | Amplifier B inverting input. Rail-to-rail common-mode range (VSS-0.1V to VDD+0.1V). Input bias current 1pA typ. |+| 7 | OUTB | output | Amplifier B output. Rail-to-rail output swing; typically <5mV from either rail with RL >100kΩ, 30mV with 10kΩ. Sources/sinks up to ~60mA short-circuit current. |+| 8 | VDD | power_in | Positive supply, 2.1V to 5.5V single-supply (or +1.05V to +2.75V dual-supply). Bypass with a 0.1µF ceramic capacitor close to this pin. Absolute max VDD-VSS = 7.5V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Gainsil |+| Package | SOP-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `GS358-SR`+- `GS358-SRMR`+- `GS358-SRDR`+- `GS358-SRFR`++## CAD (KiCad official)++- Symbol: `GS358-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/gs358-sr-datasheet.pdf) (16 pp, sha256 `3270b91a8ee80e05`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
