UG-059 Evaluation Board User Guide USING THE USB SOFTWARE The main control panel for the AD5504 software is shown in Figure 2. Use this panel to load values to the DACs and set the status of the LDAC and CLR pins. It should be noted that when power is first applied to the AD5501/AD5504, the DACs are powered down by default. The DACs are powered up by selecting the appropriate options in the control register panel.
