# COS324HV

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

COS324HV 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 | Output of amplifier A, whose output voltage range extends to within millivolts of each supply rail. |
| 2 | -INA | input | Inverting input of amplifier A, with a voltage range from -Vs -0.3V to +Vs - 1V. |
| 3 | +INA | input | Non-inverting input of amplifier A, with the same voltage range as -IN (-Vs -0.3V to +Vs - 1V). |
| 4 | +Vs | power_in | Positive power supply (3V to 30V), bypassed with a 0.1μF capacitor placed as close to the part as possible. |
| 5 | +INB | input | Non-inverting input of amplifier B, with the same voltage range as -IN (-Vs -0.3V to +Vs - 1V). |
| 6 | -INB | input | Inverting input of amplifier B, with a voltage range from -Vs -0.3V to +Vs - 1V. |
| 7 | OUTB | output | Output of amplifier B, whose output voltage range extends to within millivolts of each supply rail. |
| 8 | OUTC | output | Output of amplifier C, whose output voltage range extends to within millivolts of each supply rail. |
| 9 | -INC | input | Inverting input of amplifier C, with a voltage range from -Vs -0.3V to +Vs - 1V. |
| 10 | +INC | input | Non-inverting input of amplifier C, with the same voltage range as -IN (-Vs -0.3V to +Vs - 1V). |
| 11 | -Vs | power_in | Negative power supply or ground; if not grounded, bypass with a 0.1μF capacitor placed as close to the part as possible. |
| 12 | +IND | input | Non-inverting input of amplifier D, with the same voltage range as -IN (-Vs -0.3V to +Vs - 1V). |
| 13 | -IND | input | Inverting input of amplifier D, with a voltage range from -Vs -0.3V to +Vs - 1V. |
| 14 | OUTD | output | Output of amplifier D, whose output voltage range extends to within millivolts of each supply rail. |
