Is this dac correct enough to build?

I will be using TPS7A4700 regulators saperate for both digital and analog sections.

I have one of those.

I sounds decent enough for have some odd design choices.

 

[rhythmsandy]

is it the same circuit?

 

[Flied Egg]

I have built the Tda1543 version (there are several DIY kits with exactly the same schematic up to the DIR9001 and then varying DAC's.

My only thoughts would be that the DIR9001 is nothing special and is very small and quite difficult to solder.

 

[Avro Arrow]

is it the same circuit?

Yes.

 

[rhythmsandy]

Yes.

so what voltage regulators you have used here?

 

[rhythmsandy]

so what voltage regulators you have used here?

can you share your schematic with regulators etc..?

 

[Avro Arrow]

I got the DAC as a kit for free.
I just used what came in the kit, the schematic
is the same as #2, above.

 

[rhythmsandy]

can you please post the pictures of it?

 

[Avro Arrow]

Here is the same kit I got.

I don't have a picture available right now...sorry (it's in a directory with a few thousand other pictures)

I did do one mod, I replaced OPA2134 with LME49990.

I bit the bullet and dug through the pictures and found one.
Here you go.
