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.
The A/D conversion result never decreases with an increase in the input voltage and has no missing
codes.

Assume quiet environment. If adjacent pins have high-frequency signals (analog or digital), Z
to be reduced to as low as 1 k to fight crosstalk effects.
