I've got one piece if that helps. Purchased (from Digikey) when starting designing my own ADC but pretty much immediately when I bought that they discontinued it so I went for AK5572 instead.
Sounds good, thanks. Will PM you.
Nice website btw!
Still after a few more pieces if anyone else has some.
Cheers

Inspector,
I will let you know of any others I find... Pm me and I can keep you posted if you like.

Best source might be to purchase an old E-MU card and desolder. It's a pretty big package - normal SOP, no SSOP.
The new kid on the block is ES9822, though.

Yes, the ESS ADC is the new kid on the block and as a result, not available to purchase for the DIYer if you have to deal with north american (and australiasian, same peeps) distro. they arent available at mouser, like some of the parts are now. you can apparently get it if you are dealing with the EU distro, but if you cant prove you are going to be buying a heap of them for product sales, they dont want to deal with you. Shitty company letting their distributors act like that IMO
Yes, I never figured out what the mumbo-jumbo about data sheets under NDA only is, especially long after the product is in everything from high end gear, LG smartphones and cheap boards from China. I think the data sheets freely downloadable at mouser are a pretty recent and welcome development. I was very surprised not find that there is few performance graphs and that guarantueed performance specs are good but not nowhere near the HD performance measured in acutal products using these chips.
Indeed. I would understand if it was bleeding edge tech and if datasheets and app notes were hyper detailed, containing privileged info, but it isnt and they arent. they are ordinary datasheets with fairly basic information and the app notes are pretty lacking in thorough characterisation and application info compared to Ti/LT/AD.
just the manual for the 8 channel eval board, not exactly an app note, but as close as ESS gets to one. hell, even for their es9311 reg, which appears to be great and well priced, has virtually no applications information and is not characterised at all. its a poor excuse for a datasheet.
Gets a bit off topic but..
From my experience working in a semiconductor company, I reckon they just want to limit the number of customer contacts and keep it under control - and even outsource this filtering to distribution. Especially if their documentation is not the greatest, and knowing their DACs have had quite a few bugs, giving everyone access to their products and documentation potentially leads to huge grow in customer support needs. And all that with only peanuts added in revenue. You're really only interested in the customers who buy enough that you can hand-hold them through the design if needed and give a good support experience to win the next socket as well.
Of course, we know a good approach to solve this problem would be to make a good enough product and documentation so that we can do design-ins without contacting their support but.. hey ho 🙂
But this bugs me as well, I really want to use ESS but I don't want to sign their NDAs. If they'd even give it to me; I tried contacting European distro but no reply. Yet their rep had even contacted me on LinkedIn in the past "if I ever need anything" - of course meaning "if you buy enough".
And no, unfortunately I don't know sources of more AK5493.

Well, occasionally, it goes the other way. Some enthusiast implements something which measures great and writes about it here or Amir measures something and then others decide to design it into their product.
There is the odd hype, too. TDA1543 comes to mind, lousy specs but a cult that was partially built here on diyaudio. But in that case, I am not aware of any product using that because of the hype.

Hi Jens,
Excellent -I will PM you, thank you.
Please note that "Inspector Gadget" expressed an interest earlier in the thread as well.
Best,
Chris

Incidentally, thanks Charles for the tip about the new ESS.
Will look into that, though their whole approach makes me wonder if they are hiding any issues at lower levels... plus my ever decreasing tolerance for the sorts of BS that syn has struggled with...
Cheers all,
