Q4
The time of the A/D clock period is dependent on the device frequency and the T
ADRES register may be read on the following T
The time for the holding capacitor to acquire the “New” input voltage when the voltage changes full scale
after the conversion (AV
50Ω.
On the following cycle of the device clock.
See Section 19.0 “10-Bit Analog-to-Digital Converter (A/D) Module” for minimum conditions when input
voltage has changed more than 1 LSb.
If the A/D clock source is selected as RC, a time of T
to be executed.
This is a minimal RC delay (typically 100 ns), which also disconnects the holding capacitor from the analog input.
