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 | OUT1 | output | Output of amplifier A (channel 1). Output voltage range extends to within millivolts of each supply rail. Output current ±10mA typical, ±28mA short-circuit. |+| 2 | -IN1 | input | Inverting input of amplifier A (channel 1). Voltage range from -Vs to +Vs; input terminals are diode-clamped to the supply rails. |+| 3 | +IN1 | input | Non-inverting input of amplifier A (channel 1). Same voltage range as -IN1 (-Vs to +Vs). |+| 4 | -Vs | power_in | Negative power supply or ground. Total supply (+Vs to -Vs) range ±2.25V to ±18V (36V max). Bypass with 0.1µF ceramic capacitor close to the pin. |+| 5 | +IN2 | input | Non-inverting input of amplifier B (channel 2). Voltage range from -Vs to +Vs. |+| 6 | -IN2 | input | Inverting input of amplifier B (channel 2). Voltage range from -Vs to +Vs; input terminals are diode-clamped to the supply rails. |+| 7 | OUT2 | output | Output of amplifier B (channel 2). Output voltage range extends to within millivolts of each supply rail. Output current ±10mA typical, ±28mA short-circuit. |+| 8 | +Vs | power_in | Positive power supply. Total supply (+Vs to -Vs) range ±2.25V to ±18V (36V max). Bypass with a 0.1µF ceramic capacitor close to the pin; a 2.2µF tantalum can be added for better performance. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | COSINE |+| Package | SOP-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `COS2177SRSR`+- `COS2177SRSR/UA`+- `COS2177SRMR/U`+- `COS2177SRMR/UA`++## CAD (KiCad official)++- Symbol: `COS2177SR`+- 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:** [COSINE datasheet](docs/cos2177sr-datasheet.pdf) (9 pp, sha256 `081dec7544ce6bdd`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
