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 | Amplifier A output. Rail-to-rail output; swing extends to within ~10mV of each supply rail with light loads (1mV at 1MOhm, 10mV at 100kOhm, 120mV at 10kOhm). |+| 2 | -IN1 | input | Inverting input of amplifier A. Voltage range from -Vs-0.3V to +Vs+0.3V; input terminals are diode-clamped to the supply rails and should be current-limited to 10mA if driven beyond rails. |+| 3 | +IN1 | input | Non-inverting input of amplifier A. Same voltage range as -IN1 (-Vs-0.3V to +Vs+0.3V). Rail-to-rail common-mode range. |+| 4 | -Vs | power_in | Negative power supply or ground. For single-supply operation connect to GND; for dual-supply operation bypass with a 0.1uF ceramic capacitor placed close to the pin. Total supply (+Vs to -Vs) up to 16V max. |+| 5 | +IN2 | input | Non-inverting input of amplifier B. Rail-to-rail common-mode range; voltage range from -Vs-0.3V to +Vs+0.3V. |+| 6 | -IN2 | input | Inverting input of amplifier B. Voltage range from -Vs-0.3V to +Vs+0.3V. |+| 7 | OUT2 | output | Amplifier B output. Rail-to-rail output; swing extends to within ~10mV of each supply rail with light loads. Short-circuit sourcing ~35mA, sinking ~24mA at Vs=12V. |+| 8 | +Vs | power_in | Positive power supply. Operating range 3.3V to 16V (single supply) or +/-1.75V to +/-8V (dual supply). Bypass with a 0.1uF ceramic capacitor placed close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | COSINE |+| Package | SOP-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `COS2272SRSR`+- `COS2272SRMR`++## CAD (KiCad official)++- Symbol: `COS2272SR`+- 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/cos2272sr-datasheet.pdf) (10 pp, sha256 `9be556b1c3324bd7`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
