Integral nonlinearity (INL) is the deviation of the values on
an actual transfer function from a straight line. This
straight line is either a best-straight-line fit or a line drawn
between the end points of the transfer function, once off-
set and gain errors have been nulled. INL for the
MAX11359A is measured using the end-point method.
Differential nonlinearity (DNL) is the difference between
an actual step width and the ideal value of 1 LSB. A DNL
error specification of greater than -1 LSB guarantees no
missing codes and a monotonic transfer function.
Gain error is the amount of deviation between the mea-
sured full-scale transition point and the ideal full-scale
transition point.

diately below the crystal guard ring. This helps to
isolate the crystal from noise coupling from signals
on other PCB layers.
Note: The ground plane must be in the vicinity of the
crystal only and not on the entire board.
