Data Sheet
TERMINOLOGY
Relative Accuracy
Relative accuracy 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 LSB.
Differential Nonlinearity
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. Ideally, with all 0s loaded to
the DAC and m = all 1s, c = 2n–1.
VOUT (ZERO-SCALE) = 0 V
Zero-scale error is a measure of the difference between VOUT
(actual) and VOUT (ideal), expressed in mV. It is mainly due to
offsets in the output amplifier.
Offset Error
Offset error is a measure of the difference between VOUT (actual)
and VOUT (ideal) in the linear region of the transfer function,
expressed in mV. Offset error is measured on the AD5384-5
with Code 32 loaded into the DAC register.
Gain Error
Gain Error is specified in the linear region of the output range
between VOUT = 10 mV and VOUT = AVDDx – 50 mV. It is the
deviation in slope of the DAC transfer characteristic from the
ideal and is expressed in % FSR with the DAC output unloaded.
DC Crosstalk
DC crosstalk is the dc change in the output level of one DAC at
midscale, in response to a full-scale code (all 0s to all 1s, and vice
versa) and output change of all other DACs. It is expressed in LSB.
DC Output Impedance
DC output impedance is the effective output source resistance.
It is dominated by package lead resistance.
Output Voltage Settling Time
The 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 to
full-scale input change, and is measured from the BUSY rising
edge.
Digital-to-Analog Glitch Energy
The digital-to-analog glitch energy is the amount of energy
injected into the analog output at the major code transition. It is
specified as the area of the glitch in nV-sec. It is measured by
toggling the DAC register data between 0x1FFF and 0x2000.
DAC-to-DAC Crosstalk
DAC-to-DAC crosstalk is the glitch impulse that appears at
the output of one DAC due to both the digital change and the
subsequent analog output change at another DAC. The victim
channel is loaded with midscale. DAC-to-DAC crosstalk is
specified in nV-sec.
Digital Crosstalk
Digital crosstalk is 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-sec.
Digital Feedthrough
When the device is not selected, high frequency logic activity
on the device digital inputs can be capacitively coupled both
across and through the device to show up as noise on the
VOUT 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
generated random noise. Random noise is characterized as a
spectral density (voltage per √Hertz). It is measured by loading
all DACs to midscale and measuring noise at the output. It is
measured in nV/√Hz in a 1 Hz bandwidth at 10 kHz.
