Hi guys,

I need some help on using my audio amplifier module, TDA7297. It's working fine but it gets really hot while it's operating. Basically, I can't touch the heatsink after a few minutes because it's too hot. I took measurement of the current and it went from 200mA up to 1A, sometimes. I am not sure if it's supposed to go this high. I am afraid I might burn the chip. Is it supposed to get this hot? Am I doing something wrong? Do I need a bigger heatsink?

Please give me any advice or ideas! Thanks.
