COS822SR from COSINE, in a SOIC-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 | OUTA | output | Channel A output; swings to within millivolts of each supply rail (typ. 8mV at RL=10kΩ). |
| 2 | -IN1 | input | Channel A inverting input; voltage range -Vs -0.3V to +Vs +0.3V. |
| 3 | +IN1 | input | Channel A non-inverting input; same voltage range as -IN. |
| 4 | -Vs | power_in | Negative power supply or ground; bypass with 0.1µF close to the part if not grounded. |
| 5 | +IN2 | input | Channel B non-inverting input; same voltage range as -IN. |
| 6 | -IN2 | input | Channel B inverting input; voltage range -Vs -0.3V to +Vs +0.3V. |
| 7 | OUTB | output | Channel B output; swings to within millivolts of each supply rail (typ. 8mV at RL=10kΩ). |
| 8 | +Vs | power_in | Positive power supply, 1.8V to 5.5V; place a 0.1µF bypass capacitor close to the pin. |
