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 6.
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 7.
Monotonicity
A DAC is monotonic if the output either increases or remains
constant for increasing digital input code. The AD5726 is
monotonic over its 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
V
REFP
1 LSB. Full-scale error is expressed in LSBs. A plot of
full-scale error vs. temperature can be seen in Figure 12.
Zero-Scale Error
Zero-scale error is the error in the DAC output voltage when
0x0000 (straight binary coding) is loaded to the DAC register.
Ideally, the output voltage should be V
REFN
. A plot of zero-scale
error vs. temperature can be seen in Figure 13.

Zero-Scale Error 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.
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 converter 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 given in V/μs.
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.
Power Supply Sensitivity
Power supply sensitivity indicates how the output of the DAC is
affected by changes in the power supply voltage.
Analog Crosstalk
This 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. It is expressed in dB.
