This is my best LM3886 PCB. After numerous layouts i felt satisfied with this final layout.
Made this compact PCB layout for LM3886 audio amplifier. I kept it single layer due to cost economy. The audio input and feedback network is clubbed in one area with separate grounding resistor. I have not used input capacitor in PCB, though an external input capacitor can be employed if some DC offset is noticed in audio input.
And I am very happy to receive the PCBs, its kind of a small dream come true. Its been 4 years since i got my first samples of LM3886 and i was satisfied with home made PCBs, but recently i got some free time to learn PCB software (eagle) and it helped me to fine tune LM3886 PCB. Will upload the finished PCB and audio testing shortly.

Hi,
It's possible to add a potentiometer for control the volume ?
