# COS8092SR

**COSINE** · Operational Amplifier · SOP-8

COS8092SR from COSINE, in a SOP-8. 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 | OUT1 | output | Channel 1 output; the output voltage range extends to within millivolts of each supply rail. |
| 2 | -IN1 | input | Channel 1 inverting input; voltage range can go from -Vs -0.3V to +Vs + 0.3V. |
| 3 | +IN1 | input | Channel 1 non-inverting input; same voltage range as -IN. |
| 4 | -Vs | power_in | Negative power supply or ground; if not connected to ground, bypass with a 0.1µF capacitor as close to the part as possible. |
| 5 | +IN2 | input | Channel 2 non-inverting input; same voltage range as -IN. |
| 6 | -IN2 | input | Channel 2 inverting input; voltage range can go from -Vs -0.3V to +Vs + 0.3V. |
| 7 | OUT2 | output | Channel 2 output; the output voltage range extends to within millivolts of each supply rail. |
| 8 | +Vs | power_in | Positive power supply (2.5V to 5.5V); place a 0.1µF bypass capacitor as close to the part as possible. |
