COS324TR

COSINE · Operational Amplifier · TSSOP-14

COS324TR from COSINE, in a TSSOP-14. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUTA output Output of amplifier A. Rail-to-rail output; voltage range extends to within millivolts of each supply rail (10mV with RL=10kΩ).
2 -INA input Inverting input of amplifier A. Input voltage range from -Vs -0.3V to +Vs - 1V. Input terminals are diode-clamped to the supply rails.
3 +INA input Non-inverting input of amplifier A. Input voltage range from -Vs -0.3V to +Vs - 1V.
4 +Vs power_in Positive power supply, 2.1V to 5.5V (single supply) or +1.05V to +2.75V (dual supply). Bypass with 0.1μF ceramic capacitor placed close to the pin.
5 +INB input Non-inverting input of amplifier B. Input voltage range from -Vs -0.3V to +Vs - 1V.
6 -INB input Inverting input of amplifier B. Input voltage range from -Vs -0.3V to +Vs - 1V.
7 OUTB output Output of amplifier B. Rail-to-rail output; voltage range extends to within millivolts of each supply rail.
8 OUTC output Output of amplifier C. Rail-to-rail output; voltage range extends to within millivolts of each supply rail.
9 -INC input Inverting input of amplifier C. Input voltage range from -Vs -0.3V to +Vs - 1V.
10 +INC input Non-inverting input of amplifier C. Input voltage range from -Vs -0.3V to +Vs - 1V.
11 -Vs power_in Negative power supply or ground. For single-supply operation tie to GND; for dual supplies bypass to ground with a separate 0.1μF ceramic capacitor as close to the pin as possible.
12 +IND input Non-inverting input of amplifier D. Input voltage range from -Vs -0.3V to +Vs - 1V.
13 -IND input Inverting input of amplifier D. Input voltage range from -Vs -0.3V to +Vs - 1V.
14 OUTD output Output of amplifier D. Rail-to-rail output; voltage range extends to within millivolts of each supply rail.
