differences among these chipamps, 1875,3875 and 3886

ttan98 · 29th January 2007, 11:19 AM

I understand the 1875 has the least power output.

What about the other two, 3875 and 3886 can anyone list the differences including any sonic differences if any.

I am sure someone out there will note the differences, thanks in advance.

I tried LM1875, LM1876 and LM3886.. I've got the best sound from LM3886. May be i was some novice in LM1875 and 1876 projects and made some mistakes but i guarantee you'll satisfy the 3886s sound with a good PCB..

good PCB! how about hardwiring as there are only a few parts. I would use solid core copper wire, this would be as good if not better.

Download and browse through each chip's datasheet. There you can find differences in specs, pinouts, etc.

Or just look at my web page http://home.pacific.net.au/~gnb/audio/lmcomp.html, which compares the specs of LM4780 / 3886 / 3875 / 1875.

Yes its another way! (I tried the space montage and failed) But i guess its safer to make a PCB..

thanks Glennb most helpful,

anyone make any audio comparison,esp. between 3875 and 3886 assuming everything remains the same?
