Conversion time does not include acquisition time. See Section 20.0 “10-bit High-Speed Analog-to-Digital Converter
(A/D) Module” for a full discussion of acquisition time requirements.
In sequential modes, Tacq should be 12Tad or greater.
For V
The A/D conversion result never decreases with an incraese in the input voltage, and has no missing codes.
