Default Looking for a PCB or layout for an LME49830 amp

Hi,

are there PCB or layout files for an LME49830 amplifier? Beside the boards offered by CP Design, which has no price information on its web site at the moment ("under construction").

Did you look on the data-sheet? Just take their layout for the demo board.

If you want what is shown in the application note (AN-1850) then just go to National's site and download the Gerber files. Here is the link:

Aren't the diagrams of the board shot at 100% ? -- if so you can print the adobe file on overhead transparency material, and, using some photosensitive board -- burn your own PCB's in a bout an hour. this is what I do.

Even if the diagrams are not shot at 100% you can use the scale feature in adobe acrobat to print to your desired magnification.

Default Thanks

Hi


thanks a lot for your replies. I think I will give the gerber files a try first.

Peter

BTW: CP Design's PayPal Chart will be operational until end of the week they informed me.

If there was to be a GB for the PCB in AN-1850, I would join up.

It's a pretty darned exciting and highly flexible circuit, should suit many DIY people.

I can't figure out if the chip-pcb offering is the full schematic from AN-1850, or "similar". The layout is definitely different.
