Good/Bad Sounding Chips

[Wynand]

Is the TDA2050 considered a bad sounding chip and/or is the LM3886 much better?

Which chips spund the best?

More importantly which sound bad?

I've used a lot of TDA2050s for their simplicity and low cost, but they aren't as good as the various LM chips. They're good enough if you don't expect too much. I wouldn't bother with any of the other TDA chips, except perhaps the 2040 which is very similar in performance to the 2050.

Thank you very much, I think I'll try the LM3886 then!

Try LM3875, it has better sound than the 3886.

[Wynand]

I'll do that, thanks!!

Try LM3875, it has better sound than the 3886.

?? Really ??

The datasheet says little difference in the signal-to-noise ratio but effective it's the same: 2.0 uV noise floor (@ 4780 ratio is >= 97dB).

(No i didn't compared the chips, only have the 4780ers running because of higher power...)

I have read that 3875 sounds better than 3886, myself i have only heard the 3875 and it sounded quite good, nothing like the OPA541 tho. The OPA541 had a sound stage i never heard before, so large, wide and clear, driving the subs i had back then the room felt like water filled when i turned volume up to max but the cones barely moved at all. I never even got to make a amp before i fried the OPA`s I bought them on ebay the week before i tested them.

So we should make a design with high and mids for the opa and bass for an lm-chip?

Hello

I have recently used OPA541 and OPA549, I have used 0-36 transformer and I needed some kind of voltage splitter, so I used OPA549 for a circuit from Elektor circuits 304, I have used 4700uF on each rail from the OPA549, and 10000uF at the bridge rectifier output.

For the audio amplifier I have used OPA541, I was shocked with the sound, it was amazing indeed, although I have used 6.5" speakers, and did not expect the Bass to sound good, I was realy amazed, the Bass filled my home, not only my room. My father started yelling and shouting, turn the hummer down !! I was playing some stuff for Scooter

I went out to the garden around the home, the Bass was still digging, and I was really pleased with results that I have not expected

I will post pictures of schematics and PCB when I finish them, as I have used ugly construction method for the first time in my whole life, and it was worth the trial

Kind day
