Recommended PCB designs from Datasheets

I hope some of you could help me with this simple question. At the moment I am working on some kind of DIY project, however I would like to know if the pcb designs, that are offered in the Datasheets from for example a DAC are ok to take for your own design.

 

Here is a example from the AK4396 DAC: http://www.asahi-kasei.co.jp/akm/en/product/ak4396/ak4396_f00e.pdf

 

It starts from page 31... What do you think?

I went through the data sheet but I didn't see any PCB designs.

Maybe you are referring to the example schematics..?

 

It is not uncommon to find that even expensive designs just use the

example schematic from the data sheet...lazy engineers...

Thank you, that is exactly what I wanted to know. I am so excited about this DIY stuff, now even more, because I find it pretty difficult to design the schematics by myself, and this example stuff is big help to me.

I think it's a good start but I can't understand why they choose NE5534 as opamp because the there are lot's of other better opamps.

It might be for testing purpose only... when the time comes I will roll opamps:) I relized that I will need much more time than I thought, because first of all I have chosen a wrong development board, the wrong processor without i2s interface... long story now.
