AD5641
TERMINOLOGY
Relative Accuracy
For the DAC, relative accuracy or integral nonlinearity (INL) is
a measure of the maximum deviation, in LSBs, from a straight
line passing through the endpoints of the DAC transfer
function. See Figure 4 for a plot of typical INL vs. code.
Differential Nonlinearity (DNL)
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. This DAC is guaranteed monotonic by
design. See Figure 12 for a plot of typical DNL vs. code.
Zero-Code Error
Zero-code error is a measure of the output error when zero
code (0x0000) is loaded to the DAC register. Ideally, the output
should be 0 V. The zero-code error is always positive in the
AD5641 because the output of the DAC cannot go below 0 V.
Zero-code error is due to a combination of the offset errors in
the DAC and output amplifier. Zero-code error is expressed in
mV. See Figure 10 for a plot of zero-code error vs. temperature.
Full-Scale Error
Full-scale error is a measure of the output error when full-scale
code (0xFFFF) is loaded to the DAC register. Ideally, the output
should be V
Figure 10 for a plot of full-scale error vs. temperature.
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 ideal,
expressed as a percent of the full-scale range.
DD
− 1 LSB. Full-scale error is expressed in mV. See
Rev. C | Page 12 of 20
Total Unadjusted Error (TUE)
Total unadjusted error is a measure of the output error taking
the various errors into account. See Figure 7 for a plot of typical
TUE vs. code.
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 μV/°C.
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.
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 nV-s
and is measured when the digital input code is changed by
1 LSB at the major carry transition (0x2000 to 0x1FFF). See
Figure 26.
Digital Feedthrough
Digital feedthrough is a measure of the impulse injected into
the analog output of the DAC from the digital inputs of the
DAC, but is measured when the DAC output is not updated.
It is specified in nV-s and is measured with a full-scale code
change on the data bus, that is, from all 0s to all 1s and
vice versa.
