Integral Nonlinearity (INL)
The Integral Nonlinearity (INL) error is the maximum
deviation of an actual transfer function from an ideal
transfer function (straight line).
In the MCP47X6, INL is calculated using two end points
(zero and full scale). INL can be expressed as a per-
centage of full scale range (FSR) or in a fraction of an
LSb. INL is also called relative accuracy. Equation 7-4
shows how to calculate the INL error in LSb and
Figure 7-2 shows an example of INL accuracy.

INL ERROR

INL Accuracy Example.

Differential Nonlinearity (DNL)
The Differential Nonlinearity (DNL) error (see Figure 7-3)
is the measure of step size between codes in actual
transfer function. The ideal step size between codes is
1 LSb. A DNL error of zero would imply that every code
is exactly 1 LSb wide. If the DNL error is less than 1 LSb,
the DAC ensures monotonic output and no missing
codes. The DNL error between any two adjacent codes
is calculated as follows:
