COS4277TR

COSINE · Precision Op Amps · TSSOP-14

COS4277TR 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, whose voltage range extends to within millivolts of each supply rail.
2 -IN1 input Channel 1 inverting input, with a voltage range from -Vs to +Vs.
3 +IN1 input Channel 1 non-inverting input, with the same voltage range as -IN (-Vs to +Vs).
4 +Vs power_in Positive power supply, to be bypassed with a 0.1µF capacitor placed as close to the part as possible.
5 +IN2 input Channel 2 non-inverting input, with the same voltage range as -IN (-Vs to +Vs).
6 -IN2 input Channel 2 inverting input, with a voltage range from -Vs to +Vs.
7 OUT2 output Channel 2 output, whose voltage range extends to within millivolts of each supply rail.
8 OUT3 output Channel 3 output, whose voltage range extends to within millivolts of each supply rail.
9 -IN3 input Channel 3 inverting input, with a voltage range from -Vs to +Vs.
10 +IN3 input Channel 3 non-inverting input, with the same voltage range as -IN (-Vs to +Vs).
11 -Vs power_in Negative power supply or ground, to be bypassed with a 0.1µF capacitor placed as close to the part as possible if not connected to ground.
12 +IN4 input Channel 4 non-inverting input, with the same voltage range as -IN (-Vs to +Vs).
13 -IN4 input Channel 4 inverting input, with a voltage range from -Vs to +Vs.
14 OUT4 output Channel 4 output, whose voltage range extends to within millivolts of each supply rail.
