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. It is expressed in LSBs.
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.
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
with 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.
Voltage Reference TC
Voltage reference TC is a measure of the change in the reference
output voltage with a change in temperature. The reference TC
is calculated using the box method, which defines the TC as the
maximum change in the reference output over a given tempera-
ture range expressed in ppm/°C as follows;

REFmax
where:
VREFmax
is the maximum reference output measured over the
total temperature range.
VREFmin
is the minimum reference output measured over the total
temperature range.
VREFnom
is the nominal reference output voltage, 2.5 V.
TempRange
is the specified temperature range, either 0°C to
85°C or 40°C to +85°C.
