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