    ADC Tracking Time

      Is there any data available on the tracking time used by the internal ADC? I haven't been able to find that information in the datasheet.

      By tracking time I mean the length of time in which the sampling capacitor is connected to a chosen analog input. Knowing this would be very helpful for designing an ADC input circuit.


      Also would it be possible to configure the ADC so that the sample capacitor is left connected to the analog input while it is not sampling. This would make it much easier to measure high impedance, slowly changing signals such as a battery voltage.
