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

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 SLEEPinstruction 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 7-1 for minimum conditions.
