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
MAX1358B 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.
Common-mode rejection (CMR) is the ability of a
device to reject a signal that is common to both input
terminals. The common-mode signal can be either an
AC or a DC signal or a combination of the two. CMR is
often expressed in decibels.
Power-supply rejection ratio (PSRR) is the ratio of the
input supply change (in volts) to the change in the
converter output (in volts). It is typically measured in
decibels.
