Note1: 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.

µs 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).

— 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.
