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 can affect linearity

performance, especially at elevated temperatures.

3: tDPU is the time required for the ADC module to stabilize when it is turned on (AD1CON1<ADON> = 1).

During this time, the ADC result is indeterminate.
