7.18.6 MibADC Nonlinearity Error
The differential nonlinearity error shown in the figure below (sometimes referred to as differential linearity)
is the difference between an actual step width and the ideal value of 1 LSB.
Figure 7-28. Differential Nonlinearity (DNL)
The integral nonlinearity error shown in the figure below (sometimes referred to as linearity error) is the
deviation of the values on the actual transfer function from a straight line.
