eagle layout for lm4780

ELiTeHaYDeN · 20th July 2006, 01:18 PM

Hey guys, does anyone have a eagle layout, preferibly a tryed and tested one that I can use to base my design on? ( I need the actaul eagle files, so that i can export the gerber file etc and have 5 or 10 made)

im after a parallel or bridged version and also a pcb for non bridged/parallel (as in stereo)

im looking to build a 3 stereo versions(6 channels) and 1 bridge parallel version(sub) for 5.1 sound system.

Cheers.

I want to underline this (lol)

If someone can, please post some Lm4780 bridged mono eagle PCBs

If they're short on those eagle files...i may have to make one

I posted all the Eagle files for a single sided LM4780 pcb a couple of months ago, you should be able to modify them for your own use easily enough.

first time making a pcb for one of these, could someone give me some feedback/double check this design for me?

ELiTeHaYDeN · 23rd July 2006, 03:38 PM

can anyone go over this design for me? what size holes are suggested for the caps and resistors/lm4780

its a copy of a early bryanGT pcb

Oh if only we could have that same design except if it were in eagle

...

There must be a way to do it, if Brian GT is up for it.

Or if he's just using this design privately : ( It's up to him.

djexprice, do you have a .sch and .brd file from your own attempt at a lm4780 bridged ?
If you can provide me with those i might give it a try (i'm bored)

With kind regards,

well im getting some other pcbs made, so im going to get 20 or so of the one i drew up, seem alright to me, ive made quite a few changes since the attached above image, eg hole sizes, track widths, added a few filter caps

theres one PCB(non-amp) of mine I NEED made, but ordering just one is a waste of time so ill 20 of these pcbs + the one i need, so i guess we'll see how it goes. ( Ijust tile them and pay one design free)

gonna cost me about $28bucks US shipped for 20 of them with no silkscreen or soldermask, double sided...so its not too bad if it doesnt work i guess.. if it does, then great...

but nobody seems interested in checking it over for me/confirming its ok.

elitehayden, its hard to check without a schematic...
I'm off to work now

With kind regards,

Klaas

gosh, out of everyone thats made a lm4780 pcb, no ones willing to put the gerber output files ready for pcb manufactor(include credits all over the board, i dont care, i just want a working pcb, lol), or the original eagle files up?

or even a PROVEN working layout, as i see that bryans layout that i tried to copy is not that is being used, so i need to redo it
