— 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.,
4.1 mV @ 4.096V) from the last
sampled voltage (as stored on
CHOLD).

TGO Q4 to A/D Clock
Start
— TOSC/2 + TCY —
— 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 5.0V, 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 Table 9-1 for minimum conditions.
