TERMINOLOGY
Relative Accuracy or Integral Nonlinearity (INL)
For the DAC, 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. A typical
INL vs. code plot can be seen in Figure 7.
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. This DAC is guaranteed monotonic. A typical DNL
vs. code plot can be seen in Figure 8.
Monotonicity
A DAC is monotonic if the output either increases or remains
constant for the increasing digital input code. The AD5763 is
monotonic over its full operating temperature range.
Bipolar Zero Error
Bipolar zero error is the deviation of the analog output from the
ideal half-scale output of 0 V when the DAC register is loaded
with 0x8000 (offset binary coding) or 0x0000 (twos complement
coding). A plot of bipolar zero error vs. temperature can be seen
in Figure 13.
Bipolar Zero Temperature Coefficient (TC)
Bipolar zero TC is the measure of the change in the bipolar zero
error with a change in temperature. It is expressed in ppm FSR/°C.
Full-Scale Error
Full-scale error is a measure of the output error when full-scale
code is loaded to the DAC register. Ideally, the output voltage
should be 2 × VREF 1 LSB. Full-scale error is expressed in
percentage of full-scale range.
Negative Full-Scale Error/Zero-Scale Error
Negative full-scale error is the error in the DAC output voltage
when 0x0000 (offset binary coding) or 0x8000 (twos complement
coding) is loaded to the DAC register. Ideally, the output voltage
should be 2 × VREF. A plot of zero-scale error vs. temperature
can be seen in Figure 12.
Output Voltage Settling Time
Output voltage settling time is the amount of time it takes for the
output to settle to a specified level for a full-scale input change.
Slew Rate
The slew rate of a device is a limitation in the rate of change
of the output voltage. The output slewing speed of a voltage-
output DAC is usually limited by the slew rate of the amplifier
used at its output. Slew rate is measured from 10% to 90% of
the output signal and is expressed in volts per microsecond.
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. A plot
of gain error vs. temperature can be seen in Figure 14.
Total Unadjusted Error (TUE)
TUE is a measure of the output error considering all the various
errors.
Zero-Scale Error Temperature Coefficient (TC)
Zero-scale error TC is a measure of the change in zero-scale
error with a change in temperature. Zero-scale error TC is
expressed in ppm FSR/°C.
Gain Error Temperature Coefficient (TC)
Gain error TC is a measure of the change in gain error with
changes in temperature. Gain error TC is expressed in ppm
FSR/°C.
Digital-to-Analog Glitch Energy
Digital-to-analog glitch energy 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-sec and
is measured when the digital input code is changed by 1 LSB at the
major carry transition glitch (0x7FFF to 0x8000) (see Figure 20).
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-sec and measured with a full-scale code change
on the data bus, that is, from all 0s to all 1s, and vice versa.
Power Supply Sensitivity
Power supply sensitivity indicates how the output of the DAC
is affected by changes in the power supply voltage.
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 while
monitoring another DAC, and is expressed in LSB.
DAC-to-DAC Crosstalk
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 by
a full-scale code change (all 0s to all 1s and vice versa) with
LDAC low and monitoring the output of another DAC. The
energy of the glitch is expressed in nV-sec.
Channel-to-Channel Isolation
Channel-to-channel isolation is the ratio of the amplitude of the
signal at the output of one DAC to a sine wave on the reference
input of another DAC. It is measured in decibels.
Digital Crosstalk
Digital crosstalk is a measure of the impulse injected into the
analog output of one DAC from the digital inputs of another
DAC, but is measured when the DAC output is not updated.
It is specified in nV-sec and measured with a full-scale code
change on the data bus, that is, from all 0s to all 1s, and vice versa.
