TERMINOLOGY
Integral Nonlinearity (INL)
Integral nonlinearity, or endpoint linearity, is a measure of the
maximum deviation from a straight line passing through the
endpoints of the DAC transfer function. It is measured after
adjusting for zero-scale error and full-scale error and is
expressed in least significant bits (LSB).
Differential Nonlinearity (DNL)
Differential nonlinearity is the difference between the measured
change and the ideal 1 LSB change between any two adjacent
codes. A specified differential nonlinearity of 1 LSB maximum
ensures monotonicity.
Zero-Scale Error
Zero-scale error is the error in the DAC output voltage when
all 0s are loaded into the DAC register. Zero-scale error is a
measure of the difference between VOUT (actual) and VOUT
(ideal), expressed in millivolts (mV), when the channel is at its
minimum value. Zero-scale error is mainly due to offsets in the
output amplifier.
Full-Scale Error
Full-scale error is the error in the DAC output voltage when all
1s are loaded into the DAC register. Full-scale error is a measure
of the difference between VOUT (actual) and VOUT (ideal),
expressed in millivolts, when the channel is at its maximum
value. Full-scale error does not include zero-scale error.
Gain Error
Gain error is the difference between full-scale error and
zero-scale error. It is expressed as a percentage of the full-
scale range (FSR).
Gain Error = Full-Scale Error Zero-Scale Error
VOUT Temperature Coefficient
The VOUT temperature coefficient includes output error
contributions from linearity, offset, and gain drift.
DC Output Impedance
DC output impedance is the effective output source resistance.
It is dominated by package lead resistance.
DC Crosstalk
The DAC outputs are buffered by op amps that share common
VDD and VSS power supplies. If the dc load current changes in
one channel (due to an update), this change can result in a
further dc change in one or more channel outputs. This effect is
more significant at high load currents and is reduced as the load
currents are reduced. With high impedance loads, the effect is
virtually immeasurable. Multiple VDD and VSS terminals are
provided to minimize dc crosstalk.
Output Voltage Settling Time
Output voltage settling time is the amount of time it takes for
the output of a DAC to settle to a specified level for a full-scale
input change.
Digital-to-Analog Glitch Energy
Digital-to-analog glitch energy is the amount of energy that is
injected into the analog output at the major code transition. It
is specified as the area of the glitch in nV-s. It is measured by
toggling the DAC register data between 0x1FFF and 0x2000.
Channel-to-Channel Isolation
Channel-to-channel isolation refers to the proportion of input
signal from the reference input of one DAC that appears at the
output of another DAC operating from another reference. It is
expressed in decibels and measured at midscale.
DAC-to-DAC Crosstalk
DAC-to-DAC crosstalk is the glitch impulse that appears at the
output of one converter due to both the digital change and
subsequent analog output change at another converter. It is
specified in nV-s.
Digital Crosstalk
Digital crosstalk is defined as the glitch impulse transferred to
the output of one converter due to a change in the DAC register
code of another converter. It is specified in nV-s.
Digital Feedthrough
When the device is not selected, high frequency logic activity
on the digital inputs of the device can be capacitively coupled
both across and through the device to appear as noise on the
VOUTx pins. It can also be coupled along the supply and
ground lines. This noise is digital feedthrough.
Output Noise Spectral Density
Output noise spectral density is a measure of internally gener-
ated random noise. Random noise is characterized as a spectral
density (voltage per √Hz). It is measured by loading all DACs
to midscale and measuring noise at the output. It is measured
in nV/√Hz.
