Note 1: 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.

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 sam-

pled voltage (as stated on

CHOLD).

— 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.

† Data in “Typ” column is at 5V, 25°C unless otherwise stated. These parameters are for design guidance only

and are not tested.

Note 1: ADRES register may be read on the following TCY cycle.
