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 | OUTPUT1 | output | Amplifier A output. Push-pull output stage with typical 45 mA source / 80 mA sink capability driving loads >= 2 kOhm. |+| 2 | INPUT1- | input | Amplifier A inverting input. Typical input bias current 150 nA, input offset current 5 nA, differential input voltage max +/-30 V. |+| 3 | INPUT1+ | input | Amplifier A non-inverting input. Common-mode range typ +/-13.5 V on +/-15 V supplies; input voltage max +/-15 V. |+| 4 | VEE | power_in | Negative supply rail. Accepts down to -18 V (dual supply) or GND for single-supply operation up to +36 V total. |+| 5 | INPUT2+ | input | Amplifier B non-inverting input. Common-mode range typ +/-13.5 V on +/-15 V supplies; input voltage max +/-15 V. |+| 6 | INPUT2- | input | Amplifier B inverting input. Typical input bias current 150 nA, input offset current 5 nA, differential input voltage max +/-30 V. |+| 7 | OUTPUT2 | output | Amplifier B output. Push-pull output stage with typical 45 mA source / 80 mA sink capability driving loads >= 2 kOhm. |+| 8 | VCC | power_in | Positive supply rail. Accepts up to +20 V absolute max; recommended supply +/-2 V to +/-18 V dual or up to 36 V single. Typical quiescent current 4 mA (no load). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Gainsil |+| Package | SOP-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `GS4580-SRSR`+- `GS4580-SRTR`+- `GS4580-SRDR`++## CAD (KiCad official)++- Symbol: `GS4580-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/gs4580-sr-datasheet.pdf) (10 pp, sha256 `c3128ca1ac5a204c`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
