Hello again, I an in the process of putting one of your DACs together and I have a few things I need to get sorted out. I got the bare PCB and no components and it is the L1-L4 thats causing my problems, there aren't any specs listed in the schematic, neither on the partslist.

So, could you tell med the values and tolerances on these four inductors?

And one more thing. C5a and C5b? There are only room for one C5 on the board.

The DAC in question

(I would send Damien a mail but no contactlink is specified, at least not when I checked a few minutes ago)

Kind regards
K.

Actually, when you check attached schematic, L1-L4 are marked as PLK1077 (Panasonic) and P9818 (Panasonic); those are DigiKey part numbers.

With a Green board you use only C5; C5a and C5b is with respect to all in one board where power traces are longer and two separate caps are being used.

Hi Peter,

I have a question about the scheme you posted here. Shouldn't pin 13 also be grounded?

Thanks!

Pin 13 can be grounded or not; in my board it's not.

Somebody asked me about it few years ago and I did some comparisons and IIRC not grounded sounded better.

Ok, thanks for your reply. Something new to experiment with!

Another question (it's been asked before but I can't find a clear answer): I want to place a led on my board to check if the signal is locked into the receiver. If it's locked, I want the led to go out. Is there a way to do that?

It surely can be done, maybe using transistor driving a relay?
However, why would you need it a LED; unless something is broken the DAC is always locked
