COS9061TR

COSINE · Operational Amplifier · SOT23-5

COS9061TR from COSINE, in a SOT23-5. 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 OUT output Amplifier output, whose voltage range extends to within millivolts of each supply rail.
2 -Vs power_in Negative power supply or ground; if not connected to ground, bypass it with a 0.1µF capacitor placed as close to the part as possible.
3 +IN input Non-inverting input of the amplifier, with a voltage range from -Vs -0.3V to +Vs +0.3V.
4 -IN input Inverting input of the amplifier, with a voltage range from -Vs -0.3V to +Vs +0.3V.
5 +Vs power_in Positive power supply, 1.8V to 7.0V, with a 0.1µF bypass capacitor placed as close to the part as possible.
