Another Single Side LM4780 Board..

Dxvideo · 27th January 2007, 09:02 AM

Hi all,

I designed a SS LM4780 board. Because i have a pair of LM4780 but still i dont know what will i do with them.
Please have a look and make some critics about it. I some inspired form Pink Mouse's SS design. It made on Eagle 4.16r1 and the component from Pink Mouse's board. I downloaded LM library from CAD soft site but LM4780 is not suit on dimensions. So i had you use Pinks component. Anyway i can send it who wants.

Looks good. Two points. You want the star ground on one of the other ground connections, not the input ground, and two, turn off the islands for your copper flood.

Oh, and I personally hate curved tracks, aesthetically speaking, but that's just me, and it won't affect operation at all!

Should i determine another star point?

Like that;

A better view.. And simplified input/output terminals.

Any comment?

Probably because just about everything that can be said about chip amp layouts has already been stated in one thread or another.

You still haven't moved the star ground to one of the ground pins.

Hmm.. This is a misunderstaning... Should i move it an independent point?

Star on GND 4, with a link to SG.

Or use your original layout and link that star to GND1, then GND1 and 2 run back to the chassis ground.
