WILLSEMI(Will Semicon) · Operational Amplifier · TSSOP-14

WS72144H-14 from WILLSEMI(Will Semicon), 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; the datasheet gives an unlimited output short-circuit duration, with short-circuit current of 10 to 15 mA sink or source.
2 -INA input Inverting input of amplifier A; input common-mode voltage must stay within (V-)-0.3 V to (V+)+0.3 V.
3 +INA input Non-inverting input of amplifier A; input common-mode voltage must stay within (V-)-0.3 V to (V+)+0.3 V.
4 V+ power_in Positive supply; the supply voltage (V+)-(V-) must not exceed the 6 V absolute maximum.
5 +INB input Non-inverting input of amplifier B; input common-mode voltage must stay within (V-)-0.3 V to (V+)+0.3 V.
6 -INB input Inverting input of amplifier B; input common-mode voltage must stay within (V-)-0.3 V to (V+)+0.3 V.
7 OUTB output Output of amplifier B; the datasheet gives an unlimited output short-circuit duration, with short-circuit current of 10 to 15 mA sink or source.
8 OUTC output Output of amplifier C; the datasheet gives an unlimited output short-circuit duration, with short-circuit current of 10 to 15 mA sink or source.
9 -INC input Inverting input of amplifier C; input common-mode voltage must stay within (V-)-0.3 V to (V+)+0.3 V.
10 +INC input Non-inverting input of amplifier C; input common-mode voltage must stay within (V-)-0.3 V to (V+)+0.3 V.
11 V- power_in Negative supply; the supply voltage (V+)-(V-) must not exceed the 6 V absolute maximum.
12 +IND input Non-inverting input of amplifier D; input common-mode voltage must stay within (V-)-0.3 V to (V+)+0.3 V.
13 -IND input Inverting input of amplifier D; input common-mode voltage must stay within (V-)-0.3 V to (V+)+0.3 V.
14 OUTD output Output of amplifier D; the datasheet gives an unlimited output short-circuit duration, with short-circuit current of 10 to 15 mA sink or source.
