HAL3725DJ-A from TDK, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VSUP | power_in | Supply voltage input with operating range 4.5 V to 5.5 V and typical supply current of 8-13 mA. |
| 2 | GND | power_in | Ground reference (0 V). |
| 3 | TEST | input | Test input pin; recommended to connect to GND. |
| 4 | OUT | output | 12-bit ratiometric analog output with push-pull driver; also supports modulated communication for programming interface. |
| 5 | NC | unconnected | No connect pad; must be connected to GND. |
| 6 | NC | unconnected | No connect pad; must be connected to GND. |
| 7 | NC | unconnected | No connect pad; must be connected to GND. |
| 8 | NC | unconnected | No connect pad; must be connected to GND. |
