I want to know about what is best and new audio amplifier I will do a project 40w~100w audio amplifier what is important for audio amplifiers?
That's not enough. A home theater might have 8 channels or more, and the amp will support balancing speaker volume across the audible range. It will have very good specs for low distortion and such. This is a very different scenario than, say, a public address system in a stadium.I mean low noise, more powerfull for big speakers.
Can you have any suggest LM386 alternative newest? I tried using LM386 good for volume level 10 20w 4ohm speaker but when I am take the volume level increase giving noise and quality is not better.That's not enough.

Oh don't forget the "very important" oxygen free mains lead that connects to your wall socket!You will need to define 'best'.
For me 'best' would be cheapest.
Those with 'golden ears' would insist on oxygen free speaker cables and the like, distortion measured in ppm rather than %, etc.
Ah, so we're talking about ICs here, not complete amplifiers.Can you have any suggest LM386 alternative newest? I tried using LM386 good for volume level 10 20w 4ohm speaker but when I am take the volume level increase giving noise and quality is not better.
So I can't find any audio noise filter circuit I think I should use new technology IC for my little project.
I am in beginner level I understanding and learning fast I build myself a LM386 basic circuit I want to build class d amplifier I finded a circuit there is using TPA3122 and I can't find my location.I living in Turkey.Do you want to build one from scratch, or is a pre-assembled module ok? There are many many audio power amplifier modules on ebay from 1 W to hundreds.
What is your skill set for building a 40 W - 100 W amplifier, and where are you located?
I am interesting with cheapest and famous IC, I will look LM3886 and TDA2030 in my location, I trying and learning how it is working.Thank you for answerAh, so we're talking about ICs here, not complete amplifiers.
I've never used one, but others here have commented that the LM3886 is excellent. There are also quite a few mentions of TDA2030. Both of those manufacturers (and others) have a range of similar products for different power levels and so on.
You can find on EBay many amplifier modules based on these ICs, already built and ready to go. It would be hard to build your own for less money
I am reading datasheet but I can't understand, what is important for op-amp? How can I understand this? Where I should begin electronics? Please direct me and thank you for answers.Ramazan, you must read and understand the datasheets for the amplifier ICs. The datasheet for the LM386 shows an output power of only 0.56W into 8 ohms with high distortion with a 9V supply or 0.45W with low distortion. With a 12V supply the output power is only a little more but the heating is much more.
ebay amplifiers frequently use fake ICs and heatsinks too small.
