The AD1939 spec sheet doesn´t mention how volume control is implemented. Is it digital or analog?
Thanks

Hi Mårten,
The volume control in the AD1939 is digital. Please be aware that attenuating the DAC signal will degrade the DNR of the output. Please consider adjusting the signal level in your system outside the AD1939.
Best regards,

Thanks Coleman. Too bad they chose to not include a DCA in the AD1939.
