Note 1: These parameters are characterized but not tested in manufacturing.

2: Because the sample caps will eventually lose charge, clock rates below 10 kHz may affect linearity 

performance, especially at elevated temperatures.

3: The t

DPU

 is the time required for the ADC module to stabilize at the appropriate level when the module is 

turned on (AD1CON1<ADON>=‘1’). During this time, the ADC result is indeterminate.
