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, capable of swinging within ~5mV of the supply rails with light loads (>100kΩ) and 60mV with 10kΩ. Short-circuit current typically 60mA. |+| 2 | INA- | input | Inverting input of amplifier A. Rail-to-rail input, allowed common-mode range VSS-0.1V to VDD+0.1V. Input bias current typ 20pA. |+| 3 | INA+ | input | Non-inverting input of amplifier A. Rail-to-rail input, allowed common-mode range VSS-0.1V to VDD+0.1V. Input bias current typ 20pA. |+| 4 | VSS | power_in | Negative supply / ground. Single-supply operation ties this to GND; dual-supply operation accepts ±0.9V to ±2.75V. Absolute max VDD-VSS = 7.5V. Bypass to ground with a 0.1µF ceramic capacitor. |+| 5 | INB+ | input | Non-inverting input of amplifier B. Rail-to-rail input, allowed common-mode range VSS-0.1V to VDD+0.1V. Input bias current typ 20pA. |+| 6 | INB- | input | Inverting input of amplifier B. Rail-to-rail input, allowed common-mode range VSS-0.1V to VDD+0.1V. Input bias current typ 20pA. |+| 7 | OUTB | output | Output of amplifier B. Rail-to-rail output, capable of swinging within ~5mV of the supply rails with light loads (>100kΩ) and 60mV with 10kΩ. Short-circuit current typically 60mA. |+| 8 | VDD | power_in | Positive supply. Single-supply operation from +1.8V to +5.5V (absolute max VDD-VSS = 7.5V). Quiescent current typ 180µA per amplifier (360µA total). Bypass to VSS with a 0.1µF ceramic capacitor placed close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Gainsil |+| Package | MSOP-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `GS8552-MRMR`+- `GS8552-MR`+- `GS8552-MRSR`+- `GS8552-MRGS8552-SR`++## CAD (KiCad official)++- Symbol: `GS8552-MR`+- Footprint: `Package_SO:MSOP-8_3x3mm_P0.65mm`+- 3D model: MSOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Gainsil datasheet](docs/gs8552-mr-datasheet.pdf) (14 pp, sha256 `dc9b0f2b6cedff03`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
