COS4227UATR from COSINE, in a TSSOP-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 | 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 to +Vs. |
| 3 | +IN1 | input | Channel 1 non-inverting input; same voltage range as -IN (-Vs to +Vs). |
| 4 | +Vs | power_in | Positive power supply; place a 0.1µF bypass capacitor as close to the part as possible (supply 36V max between +Vs and -Vs). |
| 5 | +IN2 | input | Channel 2 non-inverting input; same voltage range as -IN (-Vs to +Vs). |
| 6 | -IN2 | input | Channel 2 inverting input; voltage range can go from -Vs to +Vs. |
| 7 | OUT2 | output | Channel 2 output; the output voltage range extends to within millivolts of each supply rail. |
| 8 | OUT3 | output | Channel 3 output; the output voltage range extends to within millivolts of each supply rail. |
| 9 | -IN3 | input | Channel 3 inverting input; voltage range can go from -Vs to +Vs. |
| 10 | +IN3 | input | Channel 3 non-inverting input; same voltage range as -IN (-Vs to +Vs). |
| 11 | -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. |
| 12 | +IN4 | input | Channel 4 non-inverting input; same voltage range as -IN (-Vs to +Vs). |
| 13 | -IN4 | input | Channel 4 inverting input; voltage range can go from -Vs to +Vs. |
| 14 | OUT4 | output | Channel 4 output; the output voltage range extends to within millivolts of each supply rail. |
