WILLSEMI Will Semicon · Operational Amplifier · DFN-8-EP(2x2)

WS72358D-8 from WILLSEMI Will Semicon, in a DFN-8-EP(2x2). 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, which swings rail-to-rail and drives 2kΩ resistive loads.
2 -INA input Inverting input of amplifier A.
3 +INA input Non-inverting input of amplifier A; the common-mode input range extends from (V-)-0.2V to (V+)+0.2V.
4 V- power_in Negative supply rail; single-supply operation from 1.7V to 5.5V is specified with V- as the reference.
5 +INB input Non-inverting input of amplifier B; the common-mode input range extends from (V-)-0.2V to (V+)+0.2V.
6 -INB input Inverting input of amplifier B.
7 OUTB output Output of amplifier B, which swings rail-to-rail and drives 2kΩ resistive loads.
8 V+ power_in Positive supply rail; absolute maximum supply voltage (V+)-(V-) is 6V.
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
