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).

TOSC/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.
