Legend:

Shaded cells are outside of recommended range.

Note

These values violate the minimum required TAD time.

For faster conversion times, the selection of another clock source is recommended.

The ADC clock period (TAD) and total ADC conversion time can be minimized when the ADC clock is derived from the

system clock FOSC. However, the FRC clock source must be used when conversions are to be performed with the

device in Sleep mode.
