COS4348TR

COSINE · Operational Amplifier · TSSOP-14

COS4348TR 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 OUTA output Output of amplifier A, whose output voltage range extends to within millivolts of each supply rail.
2 -INA input Inverting input of amplifier A, with a voltage range from -Vs -0.3V to +Vs + 0.3V.
3 +INA input Non-inverting input of amplifier A, with the same voltage range as -IN.
4 +Vs power_in Positive power supply (1.8V to 5.5V), bypassed with a 0.1μF capacitor placed as close to the part as possible.
5 +INB input Non-inverting input of amplifier B, with the same voltage range as -IN.
6 -INB input Inverting input of amplifier B, with a voltage range from -Vs -0.3V to +Vs + 0.3V.
7 OUTB output Output of amplifier B, whose output voltage range extends to within millivolts of each supply rail.
8 OUTC output Output of amplifier C, whose output voltage range extends to within millivolts of each supply rail.
9 -INC input Inverting input of amplifier C, with a voltage range from -Vs -0.3V to +Vs + 0.3V.
10 +INC input Non-inverting input of amplifier C, with the same voltage range as -IN.
11 -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.
12 +IND input Non-inverting input of amplifier D, with the same voltage range as -IN.
13 -IND input Inverting input of amplifier D, with a voltage range from -Vs -0.3V to +Vs + 0.3V.
14 OUTD output Output of amplifier D, whose output voltage range extends to within millivolts of each supply rail.
