AD1955 volume control when external filter IF is used

Question asked by bigcrumb on Dec 8, 2016


I have just a very simple question, is volume control still working when I put AD1955 to external filter mode? I need to overcome the internal digital filter, but I still want to keep volume regulation working. Also, is the internal volume regulation dithered? I found lot a DAC chips which didn't dither after multipling (dividing) audio samples, but I presume Analog Devices wouldn't do such mistake. 


Thank you very much!
