Definitions
INL
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 offset and
gain errors have been nullified. INL for the MAX1497/
MAX1499 is measured using the endpoint method.
DNL
Differential nonlinearity (DNL) is the difference between
an actual step width and the ideal value of ±1 LSB. A
DNL error specification of less than ±1 LSB guarantees
no missing codes and a monotonic transfer function.
Rollover Error
Rollover error is defined as the absolute-value differ-
ence between a near positive full-scale reading and
near negative full-scale reading. Rollover error is tested
by applying a full-scale positive voltage, swapping
AIN+ and AIN-, and adding the results.
Zero Input Reading
Ideally, with AIN+ connected to AIN-, the MAX1497/
MAX1499 digital ADC result is 0000h. Zero input read-
ing is the measured deviation from the ideal 0x0000
and the actual measured point.
Gain Error
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
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.
Normal-Mode 50Hz and 60Hz Rejection
(Simultaneously)
Normal-mode rejection is a measure of how much output
changes when a 50Hz and a 60Hz signal is injected into
only one of the differential inputs. The MAX1497/
MAX1499 sigma-delta converter uses its internal digital
filter to provide normal-mode rejection to both 50Hz and
60Hz power-line frequencies simultaneously.
Power-Supply Rejection Ratio
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.
