Hi Jayden,
You can use the DAC3484 as four separate DACs. The only catch is that you cannot use the complex mixer in the DAC, but you can use the Fs/2 mixer.
You also cannot use the phase adjustment in the QMC block, but this would be pointless in non-complex systems. The gain in the QMC block can still be used.
The configuration files included with the DAC GUI are applicable as long as the NCO is not indicated in the file name.
Regards,
Matt Guibord
