TERMINOLOGY
Relative Accuracy (Endpoint Nonlinearity)
A measure of the maximum deviation from a straight line passing
through the endpoints of the DAC transfer function. It is mea-
sured after adjusting for zero and full scale and is normally
expressed in LSBs or as a percentage of the full-scale reading.
Differential Nonlinearity
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 (Full-Scale Error)
A measure of the output error between an ideal DAC and the
actual device output. For these DACs, ideal maximum output is

Output Leakage Current
The current that flows into the DAC ladder switches when it is
turned off. For the I

Output Current Settling Time
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
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

Digital SFDR is a measure of the usable dynamic range of the
