My 16-bit 1543 Non-Os DAC

Congratulations, it shure looks way better than mine...

Have you any hum problems?


Miguel

Nice PCB, did you made it yourself?

How does it sound?

Cheers

Andrea

I hope it sounds as good as it looks

can you post a schematic? (especially the PS)

I think it is time for a new keyboard man. : O )

Don't feel bad, my handed down MS mouse has a nice yellow tint to it

Anyways how much does it cost to have a PCB made like that? Also how do you find places that do that?

Good job though, it looks very nice.

Try LT1431 instead of TL431.
They DO sound better!

Thanks all!

Andrea,

Yes, I draw the PCB using CAD and send to the board house.

The sound is good, rich bass and musical. I think it will improve after burn-in.

Bricolo,

The configuration of the TL431 is just the usual way.
I will prepare the sch. and post it here.

Cheers

Hi mdlover

Do you have the schematic?

Board house

Dear mdlover,

Could you provide some details of the boardhouse that fabricated your PCB ? I am extremely interested. Thank you.

Hello mdlover!

Where did you got your PCB fabricated? For how much? Do they made double side PCB??

Thanks in advance.

but the sample board charge at least 1-2k for double side...

hi mdlover, long time no see!
in your sch. why dont use ferrite to seperate the gnd?
since i can hear a very little different in some oversampling DAC.
i think it can help the performance in HF...

And I've got no problems with the same board. I use standard resistors but Multicap PPMX for output. So far it seems pretty good. Now playing with the Elektor OPA627 pre and my GCs on a pair of home made speakers. The DAC soon goes into a Conrad case same as for the GCs.

Thanks a lot mdlover for the boards and TDA1543.
