a DAC is defined as the deviation between the measured and ideal incremental change in the output of the DAC, when the input changes by one
code step. It is expressed in LSB. The measured values are adjusted for Offset and Full Scale Error before calculating DNL
Integral Non-Linearity of a DAC is defined as the deviation between the measured and ideal transfer curves, after adjusting the measured transfer
curve for Offset and Full Scale Error. It is expressed in LSB.

transitions for successive A/D code outputs expressed in LSBs. The measured transfer curve is adjusted for Offset and Fullscale errors before
calculating DNL.INL
also defined as the sum of the DNL errors starting from code 00h to the code where the INL measurement is desired. The measured transfer
