Hi,

Would you tell me what's the A version advantage? Thanks!

What's the Improved FM rejection on headphone? PSRR or CMRR?

What's the New Power up on reset function? Reduce pop issue or start-up fail issue?

Hi, Jerry,

I think the main thing we did with the A version is add the POR circuit (power up on reset). This makes the device more robust and you don't have to have a particular supply sequencing like you did with the non-A version.
