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. Rail-to-rail output; swing extends to within ~5mV of each supply rail with RL=100kΩ (15mV with RL=10kΩ). Short-circuit sourcing/sinking current is ±7mA. |+| 2 | -IN1 | input | Inverting input of amplifier A. Input voltage range extends from -Vs -0.3V to +Vs +0.3V (absolute max ±0.5V beyond rails). Input bias current ±100pA typical. |+| 3 | +IN1 | input | Non-inverting input of amplifier A. Same common-mode voltage range as -IN1 (-Vs to +Vs, rail-to-rail input). Input bias current ±100pA typical. |+| 4 | -Vs | power_in | Negative supply or ground pin. In single-supply operation tie to GND; in dual-supply operation connect to negative rail. If not connected to ground, bypass with a 0.1µF capacitor as close to the part as possible. Total supply (+Vs to -Vs) must not exceed 6V. |+| 5 | +IN2 | input | Non-inverting input of amplifier B. Rail-to-rail input; common-mode range -Vs to +Vs. Input bias current ±100pA typical. |+| 6 | -IN2 | input | Inverting input of amplifier B. Input voltage range extends from -Vs -0.3V to +Vs +0.3V. Input bias current ±100pA typical. |+| 7 | OUT2 | output | Output of amplifier B. Rail-to-rail output; swing extends to within ~5mV of each supply rail with RL=100kΩ. Short-circuit sourcing/sinking current is ±7mA. |+| 8 | +Vs | power_in | Positive supply pin. Operating range 1.8V to 5.5V (absolute max 6V from -Vs). Quiescent current 55µA per amplifier at Vs=3.0V. Place a 0.1µF bypass capacitor as close to the pin as possible, between +Vs and -Vs (or between +Vs and ground). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | COSINE |+| Package | MSOP-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `COS8552MRA`+- `COS8552MRB`+- `COS8552MRC`+- `COS8552SRA`+- `COS8552SR`+- `COS8552SRC`+- `COS8552SRD`++## CAD (KiCad official)++- Symbol: `COS8552MR`+- 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:** [COSINE datasheet](docs/cos8552mr-datasheet.pdf) (12 pp, sha256 `845c61f20f164396`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
