SOFTWARE OPERATION

The EVAL-AD5344DBZ evaluation software allows the user to
program values to the input and DAC registers of each DAC
individually (see Figure 4). Ensure the LK1 position and LK2
position on the daughter board match the DAC selected on the
DAC Selection pane on the GUI.
Write to DAC Register
Select the Write to DAC Register button to load the code of the
input data control to the DAC register of the DAC. Ensure LK1
and LK2 are set up correctly.
LDAC Control
Select the Pulse LDAC button to bring the LDAC pin low and
then high, copying the data from the input registers to the DAC
registers, and updating the outputs accordingly.
Alternatively, set the LDAC pin high or low by clicking the blue
progressive disclosure button on the INTERFACE LOGIC
block. A window opens that allows the user to click the
appropriate LDAC setting, shown in Figure 4.
