Hi who is reading this request of mine,
I want to create an audio amplifier for a 4ohm speaker and 10W of power, with a maximum of 20W (PL 7 RV Visaton). I tried a circuit with cascaded LM356Ms (pre-amp and amplification) only that the speaker effect is a bit too weak and distorted and I was asked to use another component or method. I am very inexperienced and I do not know which way to turn. I had thought of using an LM 386 but I saw that it only accepts input from -0.4V to 0.4V, and realize that I have a DC input that goes from 0V to at most 3.3V, even if it normally does not exceed 1.8 V.
I have seen some IRF240s but they are too powerful I think, I also checked the tda2822m but I don't know if it's okay because it is also an old model but I don't know.
If you can recommend specific circuits or ICs for this type of application that will work in my case it would be great.
Thanks in advance. : D
