Converting a supply-relative ADC measurement to an absolute voltage value
The ADC is designed to deliver a digital value corresponding to the analog power supply and the voltage applied on the converted channel. For most application use cases, it is necessary to convert this ratio into a voltage independent of VDDA. For applications where VDDA is known and ADC converted values can use the following formula to get this absolute value:
VCHANNELx = (VDDA / FULL_SCALE) x ADCx_DATA
For applications where VDDA value is not known, you must use the internal voltage reference and VDDA can be replaced by the expression
