a new multibit DAC chip Arda technologies AT1401

hi

this might be a good news for multibit DAC lover.
a new multibit *not ΔΣ* DAC will be released from Arda technologies.
Arda Technologies - AT1401 Flagship Audio D/A Converter

there is not complete datasheet yet,
but reported it overcomes THD+N and DNR spec of PCM1704...

That DA is ridiculously good. External reference, passive iv. I'll go & sign up.

Seems to be designed for passive IV conversion, right?
Their ADC also seems to be good...

Me too, signing up ... it looks like we can start with something new ... I do even have a R+xformer+tube I/V ready to roll.

I concur with the previous Gentlemen..

It's like all dreams coming true in one shot..

The next (real) shot will be the price?

Ciao, George

Certainly looks interesting - very nice to see a differential clock input to the DAC. Wonder why the ADC doesn't have that? ADC A-A filter is b*ggered up, violating Nyquist, but response looks nice otherwise - could have been a very nice part.

meh, you guys can keep your passive IV. very cool that you can finally play around with a chip that is still in production though. I like the sound of the AT1525 cleanup phaselock loop chip. i'm going to keep an eye on it, because it does sound quite intriguing and a fresh way of doing things.

option for external reference is good, hardly unique though

abraxalito · 1st February 2011, 02:55 AM

I think its not 'still in production' rather 'still to be produced' as they're inviting input into the feature set.

qusp · 1st February 2011, 12:12 PM

not sure why you corrected me there. I realize that, I read the copy, seems they are pretty far along, was just making the distinction between it and the usual NOS of sometimes dubious origins

Nice coincidence at some other diy forum, lol:
