should be less than 2.25mV, corresponding to an output

impedance of 0.15Ω. Output impedance is typically less

than 0.030Ω. (measure DAC voltage at the output pin if

using a voltmeter.)

ZERO SCALE ERROR

SetoneoftheDACstocode0.Themeasuredoutputshould

be less than 9mV and will typically be less than 1mV.

gAIN ERROR

Set one of the DACs to code 65,535. The output voltage

0.2%.

DC CROSSTALk

Set one of the DACs to mid-scale. Connect a 250Ω resistor

10mA, respectively, when the 5V reference is being used.)

The other output should not change by more than 3.5μV

per milliamp of load current.
