A.2
This section describes the characteristics of the analog-to-digital converter.
A.2.1
The
The following constraints exist to obtain full-scale, full range results:
This constraint exists since the sample buffer amplifier can not drive beyond the power supply levels that
it ties to. If the input level goes outside of this range it will effectively be clipped.

Num C
Full accuracy is not guaranteed when differential voltage is less than 4.50 V
The minimum time assumes a final sample period of 2 ATD clocks cycles while the maximum time assumes a final sample
period of 16 ATD clocks.
