# COS2254SR

**COSINE** · Operational Amplifier · SOP-14

COS2254SR from COSINE, in a SOP-14. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUTA | output | Amplifier A output; swings to within millivolts of each supply rail (15mV typ at RL=100kΩ). |
| 2 | -INA | input | Amplifier A inverting input; voltage range -Vs -0.3V to +Vs +0.3V. |
| 3 | +INA | input | Amplifier A non-inverting input; same voltage range as -IN (-Vs -0.3V to +Vs +0.3V). |
| 4 | +Vs | power_in | Positive power supply, 3.3V to 16V, bypass with 0.1µF capacitor close to the pin. |
| 5 | +INB | input | Amplifier B non-inverting input; voltage range -Vs -0.3V to +Vs +0.3V. |
| 6 | -INB | input | Amplifier B inverting input; voltage range -Vs -0.3V to +Vs +0.3V. |
| 7 | OUTB | output | Amplifier B output; swings to within millivolts of each supply rail. |
| 8 | OUTC | output | Amplifier C output; swings to within millivolts of each supply rail. |
| 9 | -INC | input | Amplifier C inverting input; voltage range -Vs -0.3V to +Vs +0.3V. |
| 10 | +INC | input | Amplifier C non-inverting input; voltage range -Vs -0.3V to +Vs +0.3V. |
| 11 | -Vs | power_in | Negative power supply or ground; bypass with 0.1µF capacitor close to the pin if not grounded. |
| 12 | +IND | input | Amplifier D non-inverting input; voltage range -Vs -0.3V to +Vs +0.3V. |
| 13 | -IND | input | Amplifier D inverting input; voltage range -Vs -0.3V to +Vs +0.3V. |
| 14 | OUTD | output | Amplifier D output; swings to within millivolts of each supply rail. |
