WebAlthough the inherent differential nonlinearity (DNL) of the ADC will cause deviations from an ideal Gaussian distribution (for instance, some DNL is evident in Figure 2), it should be at least approximately Gaussian. If there is significant DNL, the value of σ should be calculated for several different dc input voltages and the results averaged.

Web10 apr. 2013 · DNL is often used to infer DAC monotonicity and to determine if the DAC has any missing codes. Since most modern ADCs and DACs are monotonic, DNL is usually not as useful as INL. The last static linearity specification is INL – integral non-linearity, which is also referred to as relative accuracy.
