ADC using ES9102/9112

[acko]

Hi,

I am waiting for samples of a new ADC chip continue with this project.
In the meantime, there a new DAC version already

Acko, what do you think of making a chipless 1-bit ADC similar in concept to AD1 by Grimm Audio? Wouldn't this yield a higher sound quality compared to the complexities of a multi-order Delta-Sigma conversion back and forth on a chip? This of course would be DSD, but it could be converted to PCM in the digital domain, if needed, even in real time.

Brand of the ADC if it's possible to tell please ?

I would guess the new ESS ADC chip.

I hope it's that so but I fear ESS Tech has stopped making ADC to focus on DAC chips solely :/

Sorry, I am in the vertical market actually. More of a technology user than a provider.

Couldn't agree more with DSD output. Afaik 99% of ADCs for the recording industry uses Sigma Delta ADC that is essentially high resolution DSD native and then gets chopped and changed to PCM to bring out this CD quality music for distribution. So if we are ripping Vinyl or making recordings ourselves we are the boss aren't we?

So I am hoping ESS brings out a DSD output ADC chip otherwise I have set my sights on AK5572 from you know who 😀

Acc to 1audio they seem to have a new ADC in the making,.

It has been a long while but here is the final build with ADC core, controller, power supplies, input buffer and anti-aliasing filters all on-board. Balanced line level inputs and I2S/Spdif outputs. Hi-res, up to 32bits, 384kHz 🙂

What would the cost be for such a beauty?

PM me for price and availability. Please note this ESS 9102 chip is no longer in production and no replacement in sight, afaik. Other brands hardly come close in performance! Fortunately, I have some left in stock so while they last ...
