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; swings to within ~5mV of each supply rail with RL=100kΩ (15mV with RL=10kΩ). Short-circuit source/sink current ±7mA. |+| 2 | -IN1 | input | Inverting input of amplifier A. Input common-mode voltage may range from -Vs - 0.3V to +Vs + 0.3V. Input bias current ±100pA typ. |+| 3 | +IN1 | input | Non-inverting input of amplifier A. Same voltage range as -IN1 (-Vs - 0.3V to +Vs + 0.3V); rail-to-rail input. |+| 4 | -Vs | power_in | Negative power supply or ground. If not tied to ground, bypass with a 0.1µF capacitor as close to the pin as possible. Total supply (+Vs to -Vs) is 1.8V to 5.5V (abs max 6V). |+| 5 | +IN2 | input | Non-inverting input of amplifier B. Rail-to-rail input; range -Vs - 0.3V to +Vs + 0.3V. |+| 6 | -IN2 | input | Inverting input of amplifier B. Rail-to-rail input; range -Vs - 0.3V to +Vs + 0.3V. |+| 7 | OUT2 | output | Output of amplifier B. Rail-to-rail output; swings to within ~5mV of each supply rail with RL=100kΩ. Short-circuit source/sink current ±7mA. |+| 8 | +Vs | power_in | Positive power supply, 1.8V to 5.5V (abs max 6V between +Vs and -Vs). 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 | SOP-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `COS8552SRA`+- `COS8552SR`+- `COS8552SRB`+- `COS8552SRC`+- `COS8552SRD`+- `COS8552SRCOS8552MRA`+- `COS8552SRCOS8552MRB`+- `COS8552SRCOS8552MRC`++## CAD (KiCad official)++- Symbol: `COS8552SR`+- 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/cos8552sr-datasheet.pdf) (12 pp, sha256 `845c61f20f164396`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
