    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?

    Above link shows the module I am using.

    Please give me any advice or ideas! Thanks.

    Cheap Chyneez junk is cheap. Cost less than $3? Add some heat sink.

    The link is not for a TDA7297 module.
    What is the supply voltage, how big is the heatsink?
