7.1.1 Power Supply as the Reference for External ADC

The AMR output signals of the TMAG6180-Q1 are ratiometric to the supply voltage, VCC. This enables the external ADC to use the TMAG6180-Q1 supply voltage as a reference and eliminate the errors which can arise if a separate reference voltage is used. This also enables the optimization of the external ADC input range. TI therefore recommends to use the supply voltage (VCC) as the reference for the external ADCs. TI also recommends using a 0.1µF bypass capacitor to minimize the noise on the power supply.
