Hi guys,
I use the AKM AK4430 in a DIY DAC that I also sell as a finished product.
After the fire in Japan it is impossible to source this part. Do you know of a timeline for AKM rebooting production?
In the meantime I have asked brokers for component quotes. With the prices that I get it makes financial sense to redesign the entire product around a different DAC chip.
The AK4430 is convenient in that it charge pumps its own negative supply and provides a line driver output.
If I could dream up a DAC chip it would be one with those feature, improved SNR and added MQA decode. And of course good availability. Many people point to ESS but they are only traded by brokers, not on Mouser/DigiKey/RS etc.
Thanks,
Børge

From a cursory look at the DS I'd suggest PCM5102A as a possible alternative. Its a bigger package but seems to have pretty much the same functionality. PCM5102A's SNR is better by a few dB too.
Yes, I have some experience with that part. So it is on my shortlist of replacements.
DK has 2000 of them, so supply should be OK, at least for a few weeks..

yes, mouser is finally selling the parts. although not all, as 9068 is not available there. Pity it sounds interesting and apparently quite a performer.
Borges, to save you some time, in case you havent seen these specific posts and plan to do something with ESS parts. Check post #270 and #280 here to deal with the ESS IMD hump in a direct manner
Thanks, yes, unfortunately ismosys is only EU, shaw want to step in when it comes to Australia and they are not at all friendly to DIY. the 'new' es9080 is an interesting chip too, for lower BOM digital crossovers and such.
I generally try to avoid components that can't be bought from at least two of Mouser, Farnell, DigiKey, RS.
ESS probably make nice stuff. I understand that they prefer to focus support on a few significant customers rather than investing in high-quality documentation and availability for the masses. I just wish they had been a bit more like TI and AKM before the fire.

AKM sold through Digikey, or through wholesale distributors for high volume customers. AKM datasheets aren't always the greatest either (e.g. AK4137 datasheet). Not all that different from ESS, except no NDA needed for AKM.
AKM & ESS, regarding providing real detail data a for:
. Jitter / PN figures
. using different modes as master & client or as ESS ASRC (100MHz)
. looks like face/phase loosing club 😀
. no second source as seconds territorial fab in case of fire & earthquake's
as for AKM clear communication about recovery, as Renesance went on fire too as AKM used them as alternate fab
The point as as for ADC not that large market, so ROI to consider.

Yes, Renesas - whom had offered their capacities to AKM - - had a factory fire incident shortly after..
I am generally very much not a conspiracy theories fan..
But this is just too much coincidence.
Also the AKM incident is not clear yet

AKM will be back!

Looking at both datasheets, I consider ES9023 closest to AK4430.
I have no experience with the latter.
But IMHO, backed by a few others who have audtioned both, ES9023 done right has a slight edge to PCM5102.
And it is easier to implement.
My 2 cents,
Patrick

Great to hear that they are getting back!
I have seen some funky math in the ES9022 (and possibly ES9023, don't remember) where internal registers overflow before the sigma-delta modulator. After I saw this on real data the choice was between fading on the digital side to stay on the safe side of the overflow - or go with different vendors. I chose the latter.
