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. Output voltage range extends to within millivolts (~1mV @ 100kΩ, ~8mV @ 10kΩ, ~40mV @ 2kΩ) of each supply rail. Short-circuit source/sink ~21/22mA. |+| 2 | -IN1 | input | Inverting input of amplifier A. Voltage range from -Vs -0.3V to +Vs +0.3V. Input bias current typ ±2.5pA. |+| 3 | +IN1 | input | Non-inverting input of amplifier A. Same voltage range as -IN (-Vs -0.3V to +Vs +0.3V). Rail-to-rail input. |+| 4 | +Vs | power_in | Positive power supply, 2.5V to 5.5V (single supply) or +1.25V to +2.75V (dual). Bypass with a 0.1µF ceramic capacitor placed close to the pin. |+| 5 | +IN2 | input | Non-inverting input of amplifier B. Voltage range from -Vs -0.3V to +Vs +0.3V. Rail-to-rail input. |+| 6 | -IN2 | input | Inverting input of amplifier B. Voltage range from -Vs -0.3V to +Vs +0.3V. |+| 7 | OUT2 | output | Output of amplifier B. Rail-to-rail output; swing to within millivolts of each supply rail. |+| 8 | OUT3 | output | Output of amplifier C. Rail-to-rail output; swing to within millivolts of each supply rail. |+| 9 | -IN3 | input | Inverting input of amplifier C. Voltage range from -Vs -0.3V to +Vs +0.3V. |+| 10 | +IN3 | input | Non-inverting input of amplifier C. Voltage range from -Vs -0.3V to +Vs +0.3V. Rail-to-rail input. |+| 11 | -Vs | power_in | Negative power supply or ground. For single-supply operation, tie to GND. For dual-supply, bypass to ground with a 0.1µF ceramic capacitor close to the pin. |+| 12 | +IN4 | input | Non-inverting input of amplifier D. Voltage range from -Vs -0.3V to +Vs +0.3V. Rail-to-rail input. |+| 13 | -IN4 | input | Inverting input of amplifier D. Voltage range from -Vs -0.3V to +Vs +0.3V. |+| 14 | OUT4 | output | Output of amplifier D. Rail-to-rail output; swing to within millivolts of each supply rail. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | COSINE |+| Package | TSSOP-14 |+| Category | Op-amp/Cmp |+| Pins | 14 |++## Ordering variants++- `COS724TR`+- `COS724TRCOS724SR`++## CAD (KiCad official)++- Symbol: `COS724TR`+- Footprint: `Package_SO:TSSOP-14_4.4x5mm_P0.65mm`+- 3D model: TSSOP-14 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [COSINE datasheet](docs/cos724tr-datasheet.pdf) (10 pp, sha256 `c3bf767fb360554e`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
