The integral nonlinearity error shown in Figure 25 (sometimes referred to as linearity error) is the deviation of the
values on the actual transfer function from a straight line.

Figure 25. Integral Nonlinearity (INL) Error
The absolute accuracy or total error of an MibADC as shown in Figure 26 is the maximum value of the difference
between an analog value and the ideal midstep value.
