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 may affect linearity
performance, especially at elevated temperatures.
3: The tDPU parameter is the time required for the ADC module to stabilize at the appropriate level when the
module is turned on (ADON (ADxCON1<15>) = 1). During this time, the ADC result is indeterminate.
4: Device is functional at VBORMIN < VDD < VDDMIN. Analog modules: ADC, Comparator and DAC will have
degraded performance. Device functionality is tested but not characterized. Refer to Parameter BO10 in
Table 32-11 for the minimum and maximum BOR values.
