Ok, First post of what I hope will be a few, Starting to investigate a DAC based on TDA1541 / AD1865 (only because thats what I got)
So, as part of my newbie initiation I got a dead (Marantz) CD50, but that just went to confuse me some more - pin 5 on the SAA7220 is NC right? so why does the PCB track wander off under the SAA7210? worse its attached to xsys (pin9)
AARgh! as they say - anybody got any Ideas? - I have only the Data sheet for the SAA7220 , rather than the SAA7220P/B maybe thats the key? if so does anyone have the right datasheet?
maybe Ill just use the DF1704 instead but I'd like to solve this one too..
thanks
