Here is my final pcb design for 4780 for all three purposes. Stereo, parallel and bridged. Can anyone EAGLIze it and republish as a picture.
comments are welcome.

gday mate, looking at ur pcb looks to be in order, however im not obverly sure with the set up ur planning on running. would you be able to give me some of ur info or what ever you've got, and ill run some more looks over it :)
only concern atm would be some of the rail u have, might be a tad to small, but again it might be a low voltage rail, and mightnt have any probs with it at all.
cheers mate, gimme a yell back when you can.

thanks Sanouske
The PCB as it is is ready for Reference schematic (fig.7)
as on LM4780 datasheet pdf
Blue are resistors, purple are capacitors
Extension on solder points are jumpers
Other configurations...
Mandatory jumpers - 3 near IC and 1 near SPKR.
L is parallel/bridged input
R11, R12 for parallel only. Short SPKR terminals
Install jumper between R1(1) and R2(1) for parallel only
R1, R4=short for bridged
For Bridged, swap jumper near star gnd
For 2 channels(stereo), no modifications required
C11, C12 for reference PCB schematic

| Can anyone tell me if the reference board artwork for the LM4780/1 is available full size? When I try to double the size of the drawings in the datasheet it looses definition. |
