No, its just an S/PDIF/AES3 serial interface IC : https://www.akm.com/us/en/products/audio/ak4118aeq/
For AC-3 decoding you would need something like this : https://pdf1.alldatasheet.com/datasheet-pdf/view/58137/CIRRUS/CS49330.html

I found in the pdf of AK4118A :
When combined with the multi channel codec (AK4626A or AK4628A), the two chips provide a system solution for AC-3 applications.

I read that too, I agree its rather misleading. I think assumed is there's some digital processor already which just needs those two chips to complete the implementation.
I had a look on Cirrus , but there are no active products available for Dolby Multichannel Decoding.
The CS493295 is discontinued since 2011.
Any ideas for other chips ?

You can buy the chip already implemented on a board over at Ali - https://www.aliexpress.com/item/1005002467091888.html. You might need some help with the Chinese info there though as its not in character form amenable to online translation.
Do you know other chips ? Because I'd like to develop a unit where I can get chips active available.
No, I haven't come across any other chips besides Cirrus for this function.
I rather suspect that if you wish to sell units (rather than just DIY one or two) then you'll need a Dolby license.
