Note 1: Because the sample caps will eventually lose charge, clock rates below 10 kHz can affect linearity
performance, especially at elevated temperatures.
2: t
DPU is the time required for the ADC module to stabilize when it is turned on (ADCON1<ADON> = 1).
During this time the ADC result is indeterminate.
