A/D RC Mode
A/D RC Mode
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.,
5 mV @ 5.12V) from the last sam-
pled voltage (as stated on C
If the A/D clock source is selected
as RC, a time of T
before the A/D clock starts. This
allows the SLEEP instruction to be
executed.
