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.

— 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).

134 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.

* These parameters are characterized but not tested.

† 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.

2: See Section 11.1 for minimum conditions.
