XMOS ES9822 ADC Audio Analyzer

[GILO]

Hello, I’m new here, and this is my first time posting on this forum.

I’m currently working on building an audio analyzer using XMOS 316 and the ES9822 ADC, with the ES9822 as a slave device. It works perfectly at frequencies up to 352.8kHz, and its performance is excellent.

Due to the limitations of the Topping D10B, I can only measure up to -116dB THD+N, which is the standard spec for the Topping D10B. I don’t have a better DAC at the moment, so this might not be the ES9822’s limit.

The only issue I’m facing right now is that the ES9822 is not working with XMOS at 384kHz, even though 352.8kHz works fine.

Does anyone have any ideas?View attachment 390528

Hi Lufia,

I am currently developing a prototype board based on the ES8922QPRO. Would it be possible for you to share your evaluation schematic?

now ES9822 is works fine with xmos xu316 at 384kHz SR

What was the problem?

These are all audio evaluation boards that I personally designed.

Did I understand you correctly that you are reporting that the ES9822 ADC boards are not sold anywhere?
I would like to speed up my prototyping and testing of the prototype by purchasing such a board. If this is not possible, then maybe it is possible to get documentation for my own prototyping (schematic, PCB and list of components)?

I am not sure if astute sells evaluation boards to private people but I would like to know.
What I know is that you can expect a 300$ ish price tag.
