Nov 20, 2001 · This technical article provides useful guidelines for generic and specific INL and DNL test configurations of high-speed data converters. Find out more today.

DNL value is usually specified using one of the following units: LSB or %FSV We can use the same equations explained in Offset and Gain Error sections to convert from LSB to %FSV.

Dec 9, 2022 · A plot of a DNL against the code value. DNL is also commonly expressed as minimum and maximum values across all codes. The DNL of our hypothetical ADC is between -1 LSB and +1.1 LSB.

Mar 13, 2019 · The DNL specification is a way to characterize the difference between two successive voltage levels that a DAC produces. The DNL is the maximum deviation of the output steps from the ideal analog LSb value.

Differential nonlinearity (DNL) is the deviation from the ideal difference (1 LSB) between analog input levels that trigger any two successive digital output levels. The DNL error is the maximum value of DNL found at any transition.

Today manufacturers of data converters frequently use the histogram method to verify the integral (INL) and differential (DNL) non-linearity specifications of their data converters. This approach, also referred to as code density test, is performed in the amplitude-domain of a data converter.

Dec 20, 2007 · Below are example MATLAB scripts that calculate the linearity of the MAX5889, MAX5890, and MAX5891. Each returns the codes and values for the minimum and maximum DNL and INL errors. They also generate plots showing the …

Feb 6, 2024 · To visualize DNL characteristics, plots of DNL against the code value are commonly employed, as demonstrated in Figure 2. (Figure 2: A plot of DNL against the code value) Additionally, ADC datasheets often provide comprehensive DNL specifications, such as minimum and maximum values across all codes, offering insights into the ADC’s ...

I designed 12 bit digital to analog converter, I successfully plot the transient graph of that converter. Now my question is that how to find and plot the most import parameter of converter, i.e. INL & DNL.

Feb 12, 2021 · DNL Calculation. We can calculate the DNL by comparing the number of times we saw a particular output to the number of times we expected to see it; if we saw more hits than we expected, then that output code is wider than it should be. Or more input voltages correspond to that output than we expect.
