capacitance and source resistance.
1. These values include the quantization error which is inherently 1/2 count for any A/D converter.
For the following definitions see also
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:
