I'm interested, too. I have also one question; is there a preferred input tension for this ADC?( I'm building a phono and I don't know if 1v output is good or not; my idea is phono - ADC- DSP crossover - 4 dac - 4 amplifiers )
many thanks in advance

I think this ADC chip can do the RIAA for you, so you may not need the phono.

It can do RIAA filtering but as it is shipped, only at 48Khz. To make the RIAA work at other sample rates I will need to add custom biquad filters.

It may be better to apply such a filter later in the chain in any case.

I will give more details on this as I can.

Working on it now, My guess is it will take my a few weeks - then I will send off for prototypes.

They actually changed the part since last I worked on this board, so I have bit of work to do. I have the new datasheet - so I am excited to get back on it.

Hi Russ ... well, I could almost sense excitement through your last post :-)

In the meantime a question has popped up and so, just to be sure: Are you making a solution that will (also) allow for 384 kHz/24 bit recording to a PC via USB - or are your design goals something different?

Best regards,

Jesper

I am indeed excited about it, as I plan to use it to create some high quality rips of my own vinyl.

This module will not handle the USB side of things.

There is another one for that.

Aha - so now I'm (also) curious ... Which one would that be? When checking your website I don't see such a module ... Or am I missing something?

Greetings,

Jesper

It is the USB module which is also currently under development.

It have been updated since my last prototype work since XMOS has come out with a new device.
