I had a number of attempts with this chip with quite disappointing results.
LM386 is good for nothing, but experiments.Running it at full volume to a 250mW speaker is not at all a good idea. You need a 1W speaker at least.
It is a very old integrated circuit with high gain but low power. Result: Poor quality/distorted audio output especially when newbies are building without knowing exactly what they're doing. They'll probably run it with high gain mode with high voltage signal input.
The chip was a king a 'century' ago where no general purpose amplifiers were available. Of course, it could be used for building a LM386 radio or basic power amplifier at that age.
I haven't had much exposure to TDA2822M, but recently it proved me that it affects the audio quality(suppose headphone operation) by severe background hiss(in-born phenomena). Apart from that I like this chip because it's min. supply requirement is 1.8V and bridge configuration for high power mono operation.
For all my low voltage audio applications, I use TA7368P Toshiba amplifier which is quite decent in operation considering all these facts. It's min. supply voltage is 2V. TDA7052 also a good one so use it for direct replacement for LM386!
Anyway I use LM386 for experiments because it is a basic amplifier with in-built pre-amp so I could eliminate 1 or 2 discrete stages..a good chip for experiments!
Nowadays we're talking and dealing with quality and perfection..
