TERMINOLOGY
Relative Accuracy
Relative accuracy or endpoint nonlinearity 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 and full scale and is normally expressed in
LSBs or as a percentage of the full-scale reading.
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
over the operating temperature range ensures monotonicity.
Gain Error
Gain error or full-scale error is a measure of the output error
between an ideal DAC and the actual device output. For these
DACs, ideal maximum output is V
DACs is adjustable to zero with external resistance.
Output Leakage Current
Output leakage current is the current that flows into the DAC
ladder switches when they are turned off. For the I
terminal, it can be measured by loading all 0s to the DAC and
measuring the I
Output Capacitance
Capacitance from I
Output Current Settling Time
This is the amount of time it takes for the output to settle to a
specified level for a full-scale input change. For these devices, it
is specified with a 100 Ω resistor to ground. The settling time
specification includes the digital delay from the SYNC rising
edge to the full-scale output change.
Digital-to-Analog Glitch Impulse
The amount of charge injected from the digital inputs to the
analog output when the inputs change state. This is normally
specified as the area of the glitch in either pA-s or nV-s,
depending on whether the glitch is measured as a current or
voltage signal.

Digital Feedthrough
When the device is not selected, high frequency logic activity
on the device’s digital inputs may be capacitively coupled
through the device and produce noise on the I
noise is coupled from the outputs of the device onto follow-on
circuitry. This noise is digital feedthrough.
Multiplying Feedthrough Error
This is the error due to capacitive feedthrough from the DAC
reference input to the DAC I
loaded to the DAC.
Total Harmonic Distortion (THD)
The DAC is driven by an ac reference. The ratio of the rms sum
of the harmonics of the DAC output to the fundamental value is
the THD. Usually only the lower-order harmonics, such as
second to fifth, are included.
Digital Intermodulation Distortion (IMD)
Second-order intermodulation measurements are the relative
magnitudes of the fa and fb tones generated digitally by the
DAC and the second-order products at 2fa − fb and 2fb − fa.
Compliance Voltage Range
The maximum range of (output) terminal voltage for which the
device provides the specified characteristics.
Spurious-Free Dynamic Range (SFDR)
The usable dynamic range of a DAC before spurious noise
interferes or distorts the fundamental signal. SFDR is the
measure of difference in amplitude between the fundamental
and the largest harmonically or nonharmonically related spur
from dc to full Nyquist bandwidth (half the DAC sampling rate
or f

Digital SFDR is a measure of the usable dynamic range of the
DAC when the signal is a digitally generated sine wave.
