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 | Output of amplifier A. Rail-to-rail output, can swing to within <5mV of the supply rails with a 100kΩ load and 30mV with a 10kΩ load. Source/sink capability ~84mA/75mA typical at Vs=5V. |+| 2 | INA- | input | Inverting input of amplifier A. Rail-to-rail input, common-mode range extends 100mV beyond the supply rails (VSS-0.1V to VDD+0.1V). Input bias current is 1pA typical. |+| 3 | INA+ | input | Non-inverting input of amplifier A. Rail-to-rail input, common-mode range VSS-0.1V to VDD+0.1V. Input offset voltage 2mV typical, 5.6mV max over temperature. |+| 4 | VSS | power_in | Negative supply rail (ground in single-supply operation). Single-supply range 2.1V to 5.5V referenced from VDD; also supports dual-supply operation from ±1.05V to ±2.75V. Bypass to ground with 0.1µF ceramic close to the pin. |+| 5 | INB+ | input | Non-inverting input of amplifier B. Rail-to-rail input, common-mode range VSS-0.1V to VDD+0.1V. Input bias current 1pA typical. |+| 6 | INB- | input | Inverting input of amplifier B. Rail-to-rail input, common-mode range VSS-0.1V to VDD+0.1V. |+| 7 | OUTB | output | Output of amplifier B. Rail-to-rail output; open-loop voltage gain 100dB typical with 10kΩ load, gain-bandwidth product 1MHz, slew rate 0.6V/µs. |+| 8 | VDD | power_in | Positive supply rail. Single-supply operating range 2.1V to 5.5V (absolute max VDD-VSS = 7.5V). Quiescent current 40µA per amplifier typical. Bypass with 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++- `GS358B-SR`+- `GS358B-SRMR`+- `GS358B-SRDR`+- `GS358B-SRFR`++## CAD (KiCad official)++- Symbol: `GS358B-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/gs358b-sr-datasheet.pdf) (16 pp, sha256 `a76e980b3f01f21e`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
