cycle.

Note 1: The A/D conversion result never decreases with an increase in the input voltage and has no missing codes.

2: 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.

3: VREFH current is from RA3/AN3/VREF+ pin or AVDD, whichever is selected as the VREFH source.

VREFL current is from RA2/AN2/VREF- pin or AVSS, whichever is selected as the VREFL source.
