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 least significant bits (LSBs).
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 = 2
Zero-scale error is a measure of the difference between VOUT
(actual) and VOUT (ideal) expressed in mV. It is mainly caused
by offsets in the output amplifier.
Offset Error
Offset error is a measure of the difference between VOUT
(actual) and VOUT (ideal) expressed in mV in the linear region
of the transfer function. Offset error is measured on the
AD539x-5 with code 32 loaded in the DAC register and with
code 64 loaded in the DAC register on the AD539x-3.
Gain Error
Gain error is specified in the linear region of the output range
between V
deviation in slope of the DAC transfer characteristic from ideal
and is expressed in % FSR with the DAC output unloaded.
DC Crosstalk
This 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 the output change of all other DACs. It is expressed in LSBs.
DC Output Impedance
This is the effective output source resistance. It is dominated by
package lead resistance.

Output Voltage Settling Time
This is the amount of time it takes for the output of a DAC to
settle to a specified level for a 1/4 to 3/4 full-scale input change
and measured from the rising edge of BUSY .
Digital-to-Analog Glitch Energy
This 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-s. It is measured by toggling the DAC register data
between 0x1FFF and 0x2000.
DAC-to-DAC Crosstalk
DAC-to-DAC crosstalk is defined as the glitch impulse that
appears at the output of one DAC due to both the digital change
and subsequent analog output change at another DAC. The
victim channel is loaded with midscale, and DAC-to-DAC
crosstalk is specified in nV-s.
Digital Crosstalk
The glitch impulse transferred to the output of one converter
due to a change in the DAC register code of another converter
is defined as the digital crosstalk and is specified in nV-s.
Digital Feedthrough
When the device is not selected, high frequency logic activity on
the device’s 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
This is a measure of internally generated random noise. Ran-
dom 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)
a 1 Hz bandwidth at 10 kHz.
