Note 1:

The time of the A/D clock period is dependent on the device frequency and the TAD clock divider.

ADRES register may be read on the following TCY cycle.

The time for the holding capacitor to acquire the “New” input voltage when the voltage changes full scale

after the conversion (VDD to VSS or VSS to VDD). The source impedance (RS) on the input channels is 50

.

On the following cycle of the device clock.
