Default Lm4765 Pcb

Good morning all.

For your delectation I present a simple single sided board for the LM4765 in Eagle format. This is not yet tested, but I see no reason why it shouldn't work well.

Feel free to modify as required, but keep us all updated with your experiences.

Do you have the full version of eagle...
I am trying to figure out how you get the gruondplane thing to work.

With your board file, clicking on ratsnest, nicely fills in the ground plane. on mine it just reconnects more of those little yellow wire thingies...

P.S. that trace on the top layer going to the rear row of pins is too thick, unless its supposed to connect with the two pins in the font row too...

Nordic, the red traces are wire links on the top layer, they don't touch anything.

Groundplane in four easy steps.

1) Click on one of the yellow net wires with the info tool to find out what it is called, (you can use the rename tool to call it GND or something sensible if you'd like).

2) Click the polygon tool, and type in the name you obtained above in the text box.

3) Draw your polygon, and double click to finish.

4) Click the ratsnest tool and your plane should complete itself.

Hope that helps.

Has anyone ever bothered to look at the lowly LM1875T? That would seem like a neat little chip for an ipod powered speaker or some cool PC speaker amp.

Carlos, if you search, you will find many versions of the LM1875.

Hi Pink,

As i understand you're good at Eagle Layout Editor. I use an earlier version (4.03) of Eagle and i need a simple way to coat everywhere as gnd but the lines. I hope its clear to understanding but i dont know a better way to say. Should i use the conventional method (to do by hand) or there is a simple way? Thanks a lot.

You can try the above method, it should work the same in 4.03.
