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 swings to within ~1 mV (RL=100kΩ), ~8 mV (RL=10kΩ), or ~40 mV (RL=2kΩ) of each supply rail. Short-circuit source/sink ~21/22 mA. |+| 2 | -IN1 | input | Inverting input of amplifier A (channel 1). Allowed voltage range from -Vs - 0.3V to +Vs + 0.3V; input terminals are diode-clamped to the supply rails (limit current to <=10 mA). |+| 3 | +IN1 | input | Non-inverting input of amplifier A (channel 1). Rail-to-rail common-mode range (-0.1V to Vs+0.1V typical); same voltage-range limits as -IN1. |+| 4 | -Vs | power_in | Negative power supply or ground. For single-supply operation tie to GND; for dual-supply operation bypass to ground with a 0.1 µF ceramic capacitor placed close to the pin. Total supply (+Vs to -Vs) 2.5 V to 5.5 V (abs max 6.0 V). |+| 5 | +IN2 | input | Non-inverting input of amplifier B (channel 2). Rail-to-rail common-mode range; same voltage-range limits as -IN. |+| 6 | -IN2 | input | Inverting input of amplifier B (channel 2). Allowed voltage range from -Vs - 0.3V to +Vs + 0.3V; diode-clamped to supply rails (limit current to <=10 mA). |+| 7 | OUT2 | output | Output of amplifier B (channel 2). Output voltage swings to within millivolts of each supply rail; short-circuit source/sink ~21/22 mA. |+| 8 | +Vs | power_in | Positive power supply, 2.5 V to 5.5 V (absolute max 6.0 V referenced to -Vs). Bypass with a 0.1 µF ceramic capacitor as close as possible to the pin; add a 2.2 µF tantalum for better performance. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | COSINE |+| Package | SOIC-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `COS722SRSR`+- `COS722SRMR`++## CAD (KiCad official)++- Symbol: `COS722SR`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [COSINE datasheet](docs/cos722sr-datasheet.pdf) (10 pp, sha256 `c3bf767fb360554e`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
