Data Sheet
As the default basic clock after reset is
a valid factor as early as possible. A timeframe of approx. 6000 CPU clock cycles is sufficient to ensure a
proper reset calibration. This corresponds to minimum 300 instructions (worst case: external MUX bus with
maximum waitstates). This is required for
During the reset calibration conversions can be executed (with the current accuracy). The time required for
these conversions is added to the total reset calibration time.
During the conversion the ADC’s capacitance must be repeatedly charged or discharged. The internal
resistance of the reference voltage source must allow the capacitance to reach its respective voltage level
within each conversion step. The maximum internal resistance results from the programmed conversion
timing.
Not 100% tested, guaranteed by design and characterization.
During the sample time the input capacitance
internal resistance of the analog source must allow the capacitance to reach its final voltage level within
After the end of the sample time
Values for the sample time
should be used to calculate the above timings.
