TSW3070EVM: Amplifier Interface to Current Sink DAC - Arbitrary Waveform
Generator Demonstration
8.5 Program the DAC5682Z
On the DAC5682z EVM GUI, click on DAC5682 Diagram which is located on the left side of the GUI.
Program the DAC5682z registers as necessary manually or load a saved configuration file. An example
file for loading the DAC5682z called
DLL_4X_Interp.reg5682 can be found on the provided CD. To load
this file, click on the Load Regs button on the right center side of the GUI. Navigate to the correct location,
select this file, then click on OK . The registers will be loaded and the GUI should now look as shown in
Figure 16 . If the DLL Lock light is red, make sure the pattern generator is providing a proper DCLK to the
TSW3070EVM.
