The minimum time is the amplifier
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).

TGO
Q4 to A/D clock start
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.
