TERMINOLOGY
Relative Accuracy or Integral Nonlinearity (INL)
Relative accuracy or INL is a measure of the maximum
deviation in LSBs from a straight line passing through the
endpoints of the DAC transfer function. Figure 4, Figure 5,
and Figure 6 show typical INL vs. code plots.
Differential Nonlinearity (DNL)
DNL 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 mono-
tonicity. Figure 7, Figure 8, and Figure 9 show typical DNL vs.
code plots.
Zero-Code Error
Zero-code error is a measure of the output error when zero
code (0x0000) is loaded into the DAC register. Ideally, the
output should be 0 V. The zero-code error is always positive in
the AD5066, because the output of the DAC cannot go below
0 V. Zero-code error is expressed in millivolts. Figure 17 shows
a typical zero-code error vs. supply voltage plot.
Gain Error
Gain error is a measure of the span error of the DAC. It is the
deviation in slope of the DAC transfer characteristic from the
ideal, expressed as a percentage of the full-scale range.
Gain Error Drift
Gain error drift is a measure of the change in gain error with
changes in temperature. It is expressed in (ppm of full-scale
range)/°C.
Zero-Code Error Drift
Zero-code error drift is a measure of the change in zero-code
error with a change in temperature. It is expressed in microvolts
per degrees Celsius.
Full-Scale Error
Full-scale error is a measure of the output error when a full-
scale code (0xFFFF) is loaded into the DAC register. Ideally, the
output should be VREF 1 LSB. Full-scale error is expressed as a
percentage of the full-scale range.
Digital-to-Analog Glitch Impulse
Digital-to-analog glitch impulse is the impulse injected into the
analog output when the input code in the DAC register changes
state. It is normally specified as the area of the glitch in nanovolts
per second and is measured when the digital input code is
changed by 1 LSB at the major carry transition (0x7FFF to
0x8000). See Figure 28.
DC Power Supply Rejection Ratio (PSRR)
DC PSRR indicates how the output of the DAC is affected by
changes in the supply voltage. DC PSRR is the ratio of the
change in VOUT to a change in VDD for full-scale output of the
DAC. It is measured in decibels.
DC Crosstalk
DC crosstalk is the dc change in the output level of one DAC in
response to a change in the output of another DAC. It is measured
with a full-scale output change on one DAC (or soft power-down
and power-up) while monitoring another DAC kept at midscale.
It is expressed in microvolts.
Reference Feedthrough
Reference feedthrough is the ratio of the amplitude of the signal
at the DAC output to the reference input when the DAC output
is not being updated (that is, LDAC
Digital Feedthrough
is high). It is expressed in
decibels.
Digital feedthrough is a measure of the impulse injected into
the analog output of a DAC from the digital input pins of the
device but is measured when the DAC is not being written to
(SYNC
Digital Crosstalk
held high). It is specified in nanovolts per second and
measured with one simultaneous DIN and SCLK pulse loaded
to the DAC.
Digital crosstalk is the glitch impulse transferred to the output
of one DAC at midscale in response to a full-scale code change
(all 0s to all 1s or vice versa) in the input register of another
DAC. It is measured in standalone mode and is expressed in
nanovolts per second.
Analog Crosstalk
Analog crosstalk is the glitch impulse transferred to the output
of one DAC due to a change in the output of another DAC. It is
measured by loading one of the input registers with a full-scale
code change (all 0s to all 1s or vice versa) while keeping LDAC
high and then pulsing
DAC-to-DAC Crosstalk
LDAC low and monitoring the output of
the DAC whose digital code has not changed. The area of the
glitch is expressed in nanovolts per second.
DAC-to-DAC crosstalk is the glitch impulse transferred to the
output of one DAC due to a digital code change and subsequent
output change of another DAC. This includes both digital and
analog crosstalk. It is measured by loading one of the DACs
with a full-scale code change (all 0s to all 1s or vice versa) with
LDAC
Total Harmonic Distortion (THD)
low and monitoring the output of another DAC. The
energy of the glitch is expressed in nanovolts per second.
THD is the difference between an ideal sine wave and its
attenuated version using the DAC. The sine wave is used as
the reference for the DAC, and the THD is a measure of the
harmonics present on the DAC output. It is measured in
decibels.
