Hi,

Is the DAC output Spur calculator given in the following question : 

https://e2e.ti.com/support/data-converters/f/73/t/706085?tisearch=e2e-sitesearch&keymatch=dac%25252520spurs

also relevant for DAC38J84?

I can`t figure out how to use this calculator, What fields should I fill?

Thanks,

Asaf

    Asaf,

    Yes this will be relevant. You would enter your DAC sampling rate at the top left, then bandwidth of interest using the next two entries below the DAC sample rate. The first entry is the bandwidth starting frequency and the second is the stopping frequency. The viewing bandwidth allows you to set markers to see which harmonics are falling in the band of interest. The graph will update as soon as values are entered and you press enter.

    Regards,

    Jim
