Note 1: Because the sample caps eventually loses charge, clock rates below 10 kHz may affect linearity 

performance, especially at elevated temperatures.

2: These parameters are characterized but not tested in manufacturing.
3: The t

DPU

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

turned on ADON bit (AD1CON1<15>) = ‘1’. During this time, the ADC result is indeterminate.
