A.2.3.2 3.3V Range
Table A-14
specifies the ATD conversion performance excluding any errors due to current injection,
input capacitance and source resistance.

A.2.3.3 ATD Accuracy Definitions
For the following definitions see also
Figure A-1
.
Differential Non-Linearity (DNL) is defined as the difference between two adjacent switching steps.
The Integral Non-Linearity (INL) is defined as the sum of all DNLs:
