PCB Files

Hi friends, I am sharing the PCB files (Gerber) for JAZZ3886 and JAZZ1875. These files can be used to develop PCBs professionally. Feel free to use them.

1. JAZZ3886 ( for LM3886 )

2. JAZZ1875 ( for LM1875 and TDA2050 )

LM1875 PCB / TDA2050 PCB

This PCB is designed both for LM1875 IC or TDA2050 IC. Since both the chips has similar pin configurations, so i taken that advantage to make an optimized PCB.

My best LM3886 PCB

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.
