TERMINOLOGY
Relative Accuracy or Integral Nonlinearity (INL)
For the DAC, relative accuracy or integral nonlinearity 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 16.
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. A typical DNL vs. code plot can be seen in Figure 17.
Monotonicity
A DAC is monotonic if the output either increases or remains
constant for increasing digital input code. The AD5725 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
VREFP 1 LSB. Full-scale error is expressed in LSBs. A plot of
full-scale error vs. temperature can be seen in Figure 11.
Full-Scale Error TC
Full-scale error TC is a measure of the change in full-scale error
with a change in temperature. Full-scale error TC is expressed
in ppm FSR/°C.
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 VREFN. A plot of zero-scale
error vs. temperature can be seen in Figure 12.
Zero-Scale Error 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.
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 given in V/s.
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 it 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
Analog 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. It is expressed in dB.
