TDA2822M RF interference

Good night,
I'm using a TDA2822M to drive headphones in a breadboard prototype, but the problem is the amplifier that captures every RF interference such that of power switches and electric engines.
Could this be a consequence of the high gain of the amplifier and the high input resistance, the circuit used was the same as suggest in the datasheet of the device.
Thank you very much for your atention,
Best regards,
Daniel Almeida
