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.
DNL(i) = ^V-----ⁱ--₁-^–--_L---^V-_S---^iB---^–-----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---^VB-----⁰- – n
i=1
