Because the sample caps eventually loses charge, clock rates below 10 kHz may affect linearity
performance, especially at elevated temperatures.
These parameters are characterized but not tested in manufacturing.
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).
