DAC60501: DAC update timing

Part Number: DAC60501

Hello team,

I am wondering how to update this DAC?

User can update the DAC output by rising edge of SYNC pin?
If so, the output voltage level will be set by the data written just before?

Best Regards,
Kei Kuwahara

    Hi Kuwahara-san,

    There are two methods to updating this DAC. 

    The first (and default) method is ASYNCRONOUS mode. In this mode, the DAC output will update on the rising edge of the SYNC pin with the data that was just written to the DAC.

    The second method is SYNCRONOUS mode. In this mode, the DAC will not update until you send an "LDAC" command. In this case, you can "store" a DAC value for it to change to later. Synchronous mode is often used when you want to update multiple things at once. 

    You can change the DAC mode through the SYNC register (register 2).

    Let me know if you have more questions on how these work.

    Thanks,
    Erin
