Differential nonlinearity - Wikipedia Differential nonlinearity (acronym DNL) is a commonly used measure of performance in digital-to-analog (DAC) and analog-to-digital (ADC) converters It is a term describing the deviation between two analog values corresponding to adjacent input digital values
DNL | Analog Devices Differential Nonlinearity (DNL) is a specification that appears in data-converter datasheets In an ideal D A converter, incrementing the digital code by 1 changes the output voltage by an amount that does not vary across the device's permitted range
