Hello Everyone!
As part of a bigger project I'm working on, I need a decent audio amplifier. I've tried out a couple of ICs such as lm241, lm386N, etc.. and found tda2822m works best for me. I've built a bridge circuit shown in the datasheet for the TDA2822M and it works fine, giving little distortion. I also need volume control for this, but I'm not sure where to put the pot. I've tried putting a 50k pot just before the speaker, and this works, but if the resistance is increased, one of the 10uF caps blows up. (did this twice before I figured out what was happening). So basically, my question is where is the best place to place a pot for volume control?
Thanks in advance.
