Other Parts Discussed in Thread: CC8520

For CC85xx:

What is IOVDD voltage range. It does not appear to be specified on the CC8520 datasheet. Is it the same as the overall operating range -- 2-3.6V?

Yes, it is the same 2.0-3.6V

Thank you Per.

On the reference design for the headphones, AVDD is generated from VDD with an LC filter. What are the requirements for the AVDD filtering?

Is there a breakdown of current consumption between AVDD and VDD, even roughly?
