cycle.

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

codes.

2: 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.

Note 1:

2:

If the A/D clock source is selected as RC, a time of TCY is added before the A/D clock starts. This allows the SLEEP instruction

to be executed.

This is a minimal RC delay (typically 100 ns), which also disconnects the holding capacitor from the analog input.
