WS726055D-10 from WILLSEMI Will Semicon, in a DFN2x2-10. 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. |
| 4 | V- | power_in | Negative supply; the operating supply range is 2.5 V to 5.5 V (V+ minus V-), with a 5.5 V absolute maximum supply voltage. |
| 5 | ENA | input | Enable control of Amplifier A: 1 = enable (default), 0 = disable. |
| 6 | ENB | input | Enable control of Amplifier B: 1 = enable (default), 0 = disable. |
| 7 | +INB | input | Non-inverting input of Amplifier B. |
| 8 | -INB | input | Inverting input of Amplifier B. |
| 9 | OUTB | output | Output of Amplifier B. |
| 10 | V+ | power_in | Positive supply; the operating supply range is 2.5 V to 5.5 V relative to V-, with a 5.5 V absolute maximum supply voltage. |
