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 push-pull output capable of sourcing/sinking ~60mA into a 10Ω load and swinging within ~10mV of the rails into 100kΩ. |+| 2 | INA- | input | Amplifier A inverting input. Rail-to-rail input; common-mode range extends from Vss-0.1V to VDD+0.1V. Input bias current typ 1pA. |+| 3 | INA+ | input | Amplifier A non-inverting input. Rail-to-rail input; common-mode range Vss-0.1V to VDD+0.1V. |+| 4 | VSS | power_in | Negative supply / ground for both amplifiers. In single-supply operation tie to GND; for dual-supply operation connect to the negative rail (down to -2.75V relative to VDD). |+| 5 | INB+ | input | Amplifier B non-inverting input. Rail-to-rail input; common-mode range Vss-0.1V to VDD+0.1V. |+| 6 | INB- | input | Amplifier B inverting input. Rail-to-rail input; input bias current typ 1pA. |+| 7 | OUTB | output | Amplifier B output. Rail-to-rail push-pull output; sources/sinks ~60mA into 10Ω and swings within ~10mV of the rails into light loads. |+| 8 | VDD | power_in | Positive supply, +2.1V to +5.5V (absolute max VDD-VSS = 7.5V). Bypass with a 0.1µF ceramic capacitor placed close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Gainsil |+| Package | SOP-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `GS358A-SR`+- `GS358A-SRGS358A-MR`++## CAD (KiCad official)++- Symbol: `GS358A-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/gs358a-sr-datasheet.pdf) (14 pp, sha256 `0d1e1dff8f955618`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
