WebMay 31, 2024 · In reality, the boundaries and/or lines may be unobservable, blended and/or irregular. One metric used to measure the performance of a DAC circuit is differential non-linearity (DNL). DNL refers to the deviation between two analog voltages that are produced by a DAC circuit in response to receiving two sequential digital input bits.

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. It is an important specification for measuring error in a digital-to-analog converter (DAC); the accuracy of a DAC is mainly determi… Web0x01. The DNL for those ADC is 0.5 V (1/2LSB). * integral nonlinearity (INL): It is the deviation of the transfer function from a straigt line. For DAC, it is the largest possible difference between ideal output value and actual output value for a specific input code. (eg. When you input 0x01, you expect the output to be 1 volt, the DAC instead ... lowest ignition temperature
