COS2252MR from COSINE, in a MSOP-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 (-Vs -0.3V to +Vs +0.3V). |
| 4 | -Vs | power_in | Negative power supply or ground; if not grounded, bypass with a 0.1μF capacitor placed close to the part. |
| 5 | +IN2 | input | Channel 2 non-inverting input; same voltage range as -IN (-Vs -0.3V to +Vs +0.3V). |
| 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 (2.7V to 16V operating); place a 0.1μF bypass capacitor as close to the part as possible. |
