A.4.3.1 ADC 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.
DNL(i) = ^{V-----i-1--–}--L--V-S---i--B-^–-----1- – 1
The integral non-linearity (INL) is defined as the sum of all DNLs:
n
∑ ^{INL(n) =}
DNL(i) = ^{V---1--n--L---–}-S---V-B---0-- – n
i=1
