cycle.
Note 1:
When A/D is off, it will not consume any current other than minor leakage current. The power-down current
spec includes any such leakage from the A/D module.
VREF current is from RA2/AN2/VREF- and RA3/AN3/VREF+ pins or AVDD and AVSS pins, whichever is
selected as reference input.
2: Vss ≤ VAIN ≤ VREF
3: The A/D conversion result never decreases with an increase in the input voltage and has no missing
codes.
