COS8554TRB

COSINE · Precision Op Amps · TSSOP-14

COS8554TRB 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 Output of amplifier 1; output voltage range extends to within millivolts of each supply rail.
2 -IN1 input Inverting input of amplifier 1; voltage range from -Vs -0.3V to +Vs +0.3V.
3 +IN1 input Non-inverting input of amplifier 1; same voltage range as -IN (-Vs -0.3V to +Vs +0.3V).
4 +Vs power_in Positive power supply (1.8V to 5.5V); bypass with a 0.1µF capacitor placed as close to the part as possible.
5 +IN2 input Non-inverting input of amplifier 2; same voltage range as -IN (-Vs -0.3V to +Vs +0.3V).
6 -IN2 input Inverting input of amplifier 2; voltage range from -Vs -0.3V to +Vs +0.3V.
7 OUT2 output Output of amplifier 2; output voltage range extends to within millivolts of each supply rail.
8 OUT3 output Output of amplifier 3; output voltage range extends to within millivolts of each supply rail.
9 -IN3 input Inverting input of amplifier 3; voltage range from -Vs -0.3V to +Vs +0.3V.
10 +IN3 input Non-inverting input of amplifier 3; same voltage range as -IN (-Vs -0.3V to +Vs +0.3V).
11 -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.
12 +IN4 input Non-inverting input of amplifier 4; same voltage range as -IN (-Vs -0.3V to +Vs +0.3V).
13 -IN4 input Inverting input of amplifier 4; voltage range from -Vs -0.3V to +Vs +0.3V.
14 OUT4 output Output of amplifier 4; output voltage range extends to within millivolts of each supply rail.
