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

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

performance, especially at elevated temperatures.

3: The tDPU is the time required for the ADC module to stabilize at the appropriate level when the module is

turned on (ADxCON1<ADON>=‘1’). During this time, the ADC result is indeterminate.
