-
Power The positive supply for the analog circuits (ADC, Analog

Comparators, etc.). These are separated from VDD to
minimize the electrical noise contained on VDD from affecting
the analog functions. VDDA pins must be supplied with a
voltage that meets the specification in “Recommended DC
Operating Conditions” on page 563, regardless of system
implementation.
