COS2227USR

COSINE · Precision OpAmps · SOP-8

COS2227USR from COSINE, in a SOP-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 Output of amplifier 1, with the output voltage range extending to within millivolts of each supply rail.
2 -IN1 input Inverting input of amplifier 1, with a voltage range from -Vs to +Vs.
3 +IN1 input Non-inverting input of amplifier 1, with the 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 Non-inverting input of amplifier 2, with the same voltage range as -IN (-Vs to +Vs).
6 -IN2 input Inverting input of amplifier 2, with a voltage range from -Vs to +Vs.
7 OUT2 output Output of amplifier 2, with the output voltage range extending to within millivolts of each supply rail.
8 +Vs power_in Positive power supply (±2.5V to ±18V dual supply, 36V max total); bypass with a 0.1µF capacitor placed as close to the part as possible.
