Note: The signal-ended ADC measurements are limited in their range and only guaranteed for accuracy within
the limits shown in this table. The ADC's internal design allows for measurements outside of this range
(±200 mV), but the accuracy of such measurements is not guaranteed. The maximum input voltage is of more
interest to the differential sampling where a differential measurement might be small, but a common mode
can push the actual input voltage on one of the signals towards the upper voltage limit.
