i tried making a bridge amplifier using a TDA2822M ic and the results were a little disappointing. My LM386 amplifier circuit had a higher output than the bridge amp. i can't figure out what i did wrong, i set up the circuit just like it showed in the data sheet. my problem is there is a lot of oscillation and the chip was getting really hot. it was running off of 12V DC, so i bumped it down to 9V DC, still a lot of heat, bumped it down to 5V not as much heat, but it's still a lot. I would like to know what i am doing wrong. Thanks ![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
