LM3886 PCB
 
Hi guys,

Sorry but can Anybody experted in the field give me a good decent PCB recommendation based up on the schematic of LM3886 in the page NO1 of its datasheet?

Thanks a bunch

don't build the schematic of Fig1.
It omits all the "national optional" components.

What it does mean really?
Andrew, please enlighten me about what you mean!

Thanks

read the National Datasheet.
It mentions all the optional components.

But why I need them while I need to make a simply high power amplifier out of LM3886?

You really mean reading the datsheet for those components or read the application note?

AndrewT 7th September 2011 02:38 PM

I give up.
Just build what you want.

So please give me a PCB:D
Ok, I will take a look at those components in the datasheet. Thanks for recommendation, to see if I need them.
Any other idea please?

There must be something on the net.......
Search for it.
I have something in one of the elektor books. 300 series....it works well. At least for chip amp.
But it is at my home and I'm in London till December.
Regards, Taj

Thanks Tajzmaj.

Actually I want a one layer PCB with good and trustable traces, That's why I asked my request here so that other friends help me out with a good one....

You don't seem to know much about the details, so why not just cut to the quick and buy this - it's ready-to-go:
