WS72552M-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 amplifier A. |
| 2 | -INA | input | Inverting input of amplifier A. |
| 3 | +INA | input | Non-inverting input of amplifier A; input voltage must stay between GND-0.2 V and Vs+0.2 V per the absolute maximum ratings. |
| 4 | V- | power_in | Negative supply rail, which is GND in single-supply operation from 2.5 V to 5 V. |
| 5 | +INB | input | Non-inverting input of amplifier B; input voltage must stay between GND-0.2 V and Vs+0.2 V per the absolute maximum ratings. |
| 6 | -INB | input | Inverting input of amplifier B. |
| 7 | OUTB | output | Output of amplifier B. |
| 8 | V+ | power_in | Positive supply; the part is guaranteed for 2.5 V to 5 V single-supply operation and the absolute maximum supply voltage is 6 V. |
