Couldn't help but reply... glad to see interest in the "simplest DAC ever" =)

I have several extra sets of Crystal chips (4334 and 8414) leftover from my DIY project contributed as project 85 on the ESP website. If there are enough people who want them, I could purchase them in great enough quantity lower the price -- the 8414 is a damn expensive chip!!

You have to have your SPDIF signal present at power up? I see no provision for resetting the CS8414 on your schematic... usually the 8414 won't even start decoding until it is reset (even at power up) by bringing M0-M3 high.

As for my project so far, I've just been accumulating parts and working on the output stage and power suply. Haven't found an easy to use replacement for the CS8414 yet, or a place to purchase it if I can't find a sutable replacement.

Randy, what would a one off of the 8414 cost?

I'd go for a CS8414 (and maybe a CS4334 as well) as long as the price is right. By damned expensive, is that $50, $20 or what?

But seriously, that'd be a really nice thing to do. Otherwise I'd have to use an AD1892 and only have 20bit (and it still wouldn't be as simple as the simplest DAC ever...).


EDIT: that's wasn't my schematic, just one I found. And yes I noticed that there wasn't a circuit for resetting it. But I'd obviously add it.

Hi,

Here in Sweden, the 8414 is available at http://www.elfa.se/elfa/produkter/se/20/2021965.htm (ELFA) for about 160:- SEK ($16) + vat. Though foreign people don't pay swedish vat, it could be good for you to know it's about 25% for us poor fellows that has to pay it.

Regards,

Hi there,

Don't know if it could be of any interest, but our US (and perhaps Canadian) friends can order the CS8414 from Nuhorizons for $10.09 (www.nuhorizons.com) - Min order of $25 for grand total. I did it a long time ago and haven't had any problem.

Cheers,

Ever try getting samples from them? I only need a few and am afriad I'm going to screw a few up (small wires to solder to).

I noticed they've got samples to order, just wondering if you ever had.

Hi JoeBob,

No, sorry, didn't try to get samples from them. Just ordered the whole 96 kHz Crystal bunch (8414,8420,8404) in the regular way Guess you would have to meet some requirements (e.g. be a company...) in order (What a pun !!!) to get samples, but may be it's worth a try

Oops, I thought that was your schematic... =)

I'm selling the set (4334 and 8414) for $25 and the 8414 alone for $20. Only three sets left... honestly you might be able to find them cheaper, but it's up to you.
