Integral nonlinearity is the deviation of the values on an
actual transfer function from a straight line. This straight
line can be either a best straight-line fit or a line drawn
between the endpoints of the transfer function, once
offset and gain errors have been nullified. The static lin-
earity parameters for the MAX1184 are measured using
the best straight-line fit method.
Differential nonlinearity is the difference between an
actual step-width and the ideal value of 1LSB. A DNL

error specification of less than 1LSB guarantees no
missing codes and a monotonic transfer function.
