3. The ADC channels on pins PA08, PA09, PA10, and PA11 are powered from the V
DDIO
power
supply. The ADC performance of these pins will not be the same as all the other ADC channels on
pins powered from the V
DDANA
power supply.
4. The gain accuracy represents the gain error expressed in percent. Gain accuracy (%) = (Gain Error
in V x 100) / (V
REF
/GAIN).
