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. Output voltage swing extends to within millivolts of each supply rail (typ 1mV with RL=100kΩ, 8mV with RL=10kΩ, 40mV with RL=2kΩ). Short-circuit source/sink current ~21/22 mA. |+| 2 | -Vs | power_in | Negative power supply or ground. Total supply (+Vs to -Vs) is 2.5V to 5.5V (absolute max 6.0V). If not connected to ground, bypass with a 0.1μF ceramic capacitor placed as close to the pin as possible. |+| 3 | +IN | input | Non-inverting input of the amplifier. Voltage range extends from -Vs -0.3V to +Vs +0.3V. Rail-to-rail input; input bias current typ ±2.5 pA. Input terminals are diode-clamped to the supply rails; limit current to 10mA if input swings >0.5V beyond a rail. |+| 4 | -IN | input | Inverting input of the amplifier. Voltage range extends from -Vs -0.3V to +Vs +0.3V. Rail-to-rail input; input bias current typ ±2.5 pA. Input terminals are diode-clamped to the supply rails; limit current to 10mA if input swings >0.5V beyond a rail. |+| 5 | +Vs | power_in | Positive power supply, 2.5V to 5.5V (single supply) or ±1.25V to ±2.75V (dual supply). Bypass with a 0.1μF ceramic capacitor placed as close to the pin as possible; a 2.2μF tantalum may be added for improved performance. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | COSINE |+| Package | SOT-23-5 |+| Category | Op-amp/Cmp |+| Pins | 5 |++## Ordering variants++- `COS721TRTR`+- `COS721TRSR`++## CAD (KiCad official)++- Symbol: `COS721TR`+- 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/cos721tr-datasheet.pdf) (10 pp, sha256 `c3bf767fb360554e`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
