Someone has made a driver that works for the A/D converter CS5532 or CS5534?
If you also want to share that would be fabulous!

once you decide you need to operate in 24 bit space
you have bigger issues than just the driver code.

realizing clean , accurate, low noise results from even a 16 bit
converter is demanding enough, but the analog and power supply design
has to be damned good to get results that justify the cost of the parts.

BTDT with TI parts and i kid you not in the least..... Very Happy

If you study the data sheet for this part, this is 'why' it is careful to tell you that you can use opto-couplers to drive it.
I's say it is very hard to design a board to carry this part, and directly drive it from a processor. I'd definitely be considering having an 'analog only' section to the board, probably fed with a separate analog supply, with opto-coupling back to the 'digital' section.
Circuit design for this is perhaps 50* harder than the 'driver' code.

Thanks for answering!
I understand in the field that I'm getting and complexity.
For now follow the manufacturer's recommendations (Cirrus) with respect to hardware design.
I understand that is subject to many considerations.

A question (knowing that English is not my native language):
What does the acronym BTDT??

Been There, Done That - means they have experience in that area, sometimes not a good experience...
