Default PCB required for MAX9709

Hello

I have a couple of MAX9709 ICs with me.

Can anyone design the pcb for this ic based on the application circuit in the datasheet (http://pdfserv.maxim-ic.com/en/ds/MAX9709.pdf) .
there is a evaluation kit also out here>>http://pdfserv.maxim-ic.com/en/ds/MAX9709EVKIT.pdf

Has anyone used this ic i.e implemented it as an amplifier before?

The package that i have is THIN QFN, 56 lead.

The PCB design in the evaluation kit pdf is for a 4 layer board. Those are about 3 times more expensive to make than a 2 layer board, although it is possible to make a better layout with a 4 layer board.

I haven't heard anything about this chip, but there are a lot of chips out there you never hear about. If anything, it looks to have performance similar to the low power Tripath chips, only the bridged outputs are capable of being configured in parallel for a single high current output.

The eval kit has a four layer board,which is not possible for DIY,if there is a two layer board then life would be easier.Although i have made pcb earlier ,but this is a high speed design and a unknown truff for me.
So i am looking forward to someone to design the board.
