TERMINOLOGY
Relative Accuracy or Integral Nonlinearity (INL)
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. A typical INL vs. code plot can be seen in Figure 7
Differential Nonlinearity (DNL)
Differential nonlinearity (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 monotonicity. This DAC is guaranteed
monotonic by design. 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 increasing digital input code. The AD5724R/
AD5734R/AD5754R are monotonic over their full operating
temperature range.
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 should be
full-scale − 1 LSB. Full-scale error is expressed in percent of
full-scale range (% FSR).
Zero-Scale TC
This 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
This is a measure of the span error of the DAC. It is the
deviation in slope of the DAC transfer characteristic from ideal
expressed in % FSR. A plot of gain error vs. temperature can be
seen in Table TBD
Gain TC
This is a measure of the change in gain error with changes in
temperature. Gain Error TC is expressed in ppm FSR/°C.

Total Unadjusted Error
Total unadjusted error (TUE) is a measure of the output error
taking all the various errors into account, namely INL error,
offset error, gain error, and output drift over supplies,
temperature, and time. TUE is expressed in % FSR.
Current Loop Voltage Compliance
The maximum voltage at the I
currnet will be equal to the programmed value.
Power Supply Rejection Ratio (PSRR)
PSRR indicates how the output of the DAC is affected by
changes in the power supply voltage.
Reference TC
Reference TC is a measure of the change in the reference output
voltage with a change in temperature. It is expressed in ppm/°C.
Line Regulation
Line regulation is the change in reference output voltage due to
a specified change in supply voltage. It is expressed in ppm/V.
Load Regulation
Load regulation is the change in reference output voltage due to
a specified change in load current. It is expressed in ppm/mA.
Thermal Hysteresis
Thermal hysteresis is the change of reference output voltage
after the device is cycled through temperatures from +25°C to
−40°C to +85°C and back to +25°C. This is a typical value from
a sample of parts put through such a cycle. See Table TBDfor a
histogram of thermal hysteresis.
