DEMO MANUAL DC934A

Experiments

should be less than 2.25mV, corresponding to an output

impedance of 0.15Î©. Output impedance is typically less

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

using a voltmeter.)

Gain Error

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

should be within 0.7% of VREF, and will typically be within

0.2%.

Zero Scale Error

Set one of the DACs to code 0. The measured output should

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

Offset Error

Set one of the DACs to code 256. The output voltage should

be within 9mV of the correct value, or VREF â¢ 256/65535.

DC Crosstalk

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

from the output to VCC or power ground (to sink or source

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

The other output should not change by more than 3.5Î¼V

per milliamp of load current.
