It is ratiometric to VCC, so an ADC on the same rail measures field directly, and on-chip temperature compensation holds the sensitivity flat over temperature, which older linear Hall sensors struggle with. Sensitivity options (A1-A4) trade range against resolution. Runs from 3.3 or 5 V. A precise analog sensor for position, angle, and current sensing with a magnet.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | VCC | power_in | Power supply, 3.0 to 3.63 V or 4.5 to 5.5 V.
