Note:
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.

The minimum time is the ampli-
fier settling time. This may be
used if the “new” input voltage
has not changed by more than 1
LSb (i.e., 20.0 mV @ 5.12V)
from the last sampled voltage
(as stated on CHOLD).
