DPU
These parameters are characterized but not tested in manufacturing.
Because the sample caps will eventually lose charge, clock rates below 10 kHz can affect linearity
performance, especially at elevated temperatures.
T
During this time, the ADC result is indeterminate.
DPU
is the time required for the ADC module to stabilize when it is turned on (AD1CON1<ADON> = 1).
