COS2177MR

COSINE · Precision Op Amps · MSOP-8

COS2177MR 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 to +Vs.
3 +IN1 input Channel 1 non-inverting input; same voltage range as -IN (-Vs to +Vs).
4 -Vs power_in Negative power supply or ground; if not connected to ground, bypass with a 0.1µF capacitor placed as close to the part as possible.
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 +Vs power_in Positive power supply; place a 0.1µF bypass capacitor as close to the part as possible between supply pins or between supply pins and ground.
