COS2272MR

COSINE · Operational Amplifier · MSOP-8

COS2272MR 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 connected to ground, 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 (3.3V to 16V); place a 0.1μF bypass capacitor as close to the part as possible.
