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 | OUT | output | Amplifier output. Rail-to-rail output; voltage swing extends to within ~5 mV of each supply rail (RL=100k) or ~15 mV (RL=10k). Short-circuit source/sink current ~+/-7 mA. |+| 2 | -Vs | power_in | Negative power supply or ground. If not connected to ground, bypass with a 0.1 uF capacitor as close to the part as possible. Supply range 1.8 V to 5.5 V total (+Vs to -Vs), 6 V absolute maximum. |+| 3 | +IN | input | Non-inverting input of the amplifier. Rail-to-rail input; common-mode voltage range extends from -Vs - 0.3 V to +Vs + 0.3 V. Input bias current +/-100 pA typical. |+| 4 | -IN | input | Inverting input of the amplifier. Voltage range -Vs - 0.3 V to +Vs + 0.3 V. Input bias current +/-100 pA typical; internal diode clamps to supply rails limit input current to 10 mA. |+| 5 | +Vs | power_in | Positive power supply. Operating range 1.8 V to 5.5 V (referenced to -Vs). Bypass with a 0.1 uF capacitor placed as close to the pin as possible, between +Vs and -Vs (or between +Vs and GND). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | COSINE |+| Package | SOT-23-5 |+| Category | Op-amp/Cmp |+| Pins | 5 |++## Ordering variants++- `COS8551TRA`+- `COS8551TRACOS8551TRB`+- `COS8551TRACOS8551TRC`+- `COS8551TRACOS8552SRA`+- `COS8551TRACOS8552SR`+- `COS8551TRACOS8552SRC`+- `COS8551TRACOS8552SRD`+- `COS8551TRACOS8552MRA`+- `COS8551TRACOS8552MRB`+- `COS8551TRACOS8552MRC`+- `COS8551TRACOS8554SR`+- `COS8551TRACOS8554SRB`+- `COS8551TRACOS8554SRC`+- `COS8551TRACOS8554TRA`+- `COS8551TRACOS8554TRB`+- `COS8551TRACOS8554TRC`++## CAD (KiCad official)++- Symbol: `COS8551TRA`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [COSINE datasheet](docs/cos8551tra-datasheet.pdf) (12 pp, sha256 `845c61f20f164396`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
