Part Number: DAC63204EVM
Other Parts Discussed in Thread: DAC63204

Hi, 

I am trying to configure DAC63204 in voltage out mode, using internal reference with gain 1.5, not able to see any voltage out on DMM. Can you please help with register configuration for mentioned configurations. I tried to change some configurations and clicked on Write but when I read all, all the values are 0xFFFF

    Hi Pooja, 

    The GUI is in demo mode in your screenshot. The GUI is not sending the DAC any commands while in demo mode. Can you uncheck the demo mode checkbox at the top right?

    When you are not in demo mode, you can select read all at the top of the low level page to get the register settings that are currently in the device. 

    To see a DAC output you should write 0x1249 to register 0x1F to power on . Write 0x0800 to register 0x03, 0x09, 0x0F, 0x15 to set the gain. And then write the data to register 0x19, 0x1A, 0x1B, and 0x1C. 

    Best,
