WILLSEMI Will Semicon · Operational Amplifier · MSOP-8

WS726052M-8 from WILLSEMI Will Semicon, in a MSOP-8. 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 Channel A, which the datasheet describes as rail-to-rail with 350 mA peak output drive capability.
2 -INA input Inverting input of Channel A.
3 +INA input Non-inverting input of Channel A; input common-mode range is (V-) - 0.1 V to (V+) + 0.1 V.
4 V- power_in Negative supply; operating supply range is 2.5 V to 5.5 V (V+ minus V-).
5 +INB input Non-inverting input of Channel B; input common-mode range is (V-) - 0.1 V to (V+) + 0.1 V.
6 -INB input Inverting input of Channel B.
7 OUTB output Output of Channel B, which the datasheet describes as rail-to-rail with 350 mA peak output drive capability.
8 V+ power_in Positive supply; operating supply range is 2.5 V to 5.5 V (V+ minus V-).
