Sure thanks! I will also be posting some design details here.

Cheers!

Brian,
are there any specifications for the eval board? Like THD? THD+N?


/S

Yup, they are available...

 

[Russ White]

The Eval board is what is used for the datasheet. So if you have the datasheet you have numbers.

 

[staccatiss]

OK

I do have the rev A version fo the datasheet but not for the latest ESS 9102 rev C.

I wish that ESS would publish measurement results for Fs > 44k1. My datasheet only presents results for Fs = 44k1...

i have bean looking for a affordable 384kS/s usb adc for ages without finding one, i would be happy with 192kS/s but thats also very difficult to find. i would prefer not having built it my self, i need that time for a speaker built and my studies.

hello,

any news?

 

[Russ White]

Still planning on doing this module, but the USB module has taken priority. The two will be used together, so I kind of need to get the USB module vetted first.

To Russ White
Hello
You measured IMD distortion ADC ES9102?
If measured, what znicheniya received.
Sincerely,
Sergei.

 

[Russ White]

No I have not, your best bet is to ask ESS for that kind of data.

 

[Brett]

Any update on whether you're going ahead with this design?

 

[Russ White]

It's on the back burner at the moment. I will respond on this thread when I have resumed. I have some projects which could use this module though, so I do plan on getting back to it.

Yepp - a 9102 building block would be nice! USB out as well a I2S. Possibility for clock experiments would also be appreciated.

Russ, any update on ETA for the ADC board?

Hi!

Just another hopeful request for the TPA ADC module with RIAA! It would be amazing to digitise the output immediately after the turntable (to minimise hum, interference and transmission losses) for input into a DAC with digital volume attenuation for real-time playback.

I know people will just ask why I don't digitise my vinyl with current ADCs for convenience... But I still want to play my records and also hear the changes with changes in my phono playback system. I think this would be the best modern solution to age old vinyl playback problems. The fidelity would probably also be even better than with traditional phono preamps and step-up transformers.

Anyway... I know you guys are super busy, but this is just a reminder that people are still watching this space!

Thanks!
Taz.

Actually, people would ask, why you don't listen to your vinyl without digitizing. DACs just don't sound analog, not even the ladder PCM1704K with the digital source slaved to the DAC's clock.

Also, step-up transformers come before the RIAA equalization step and no active amplifier can beat the sound quality of a good and properly matched pair of step-up transformers.

Is there any progress?

Seems that ESS ended its short ADC's adventure ...
