Heat problem in AD811ANZ

Hello all,

    I am using AD811 in my amplifier circuit.In this circuit ,I am giving 1V sine ,triangular and square wave signal at 10Hz to2MHz  to the input of amplifier.If I  use this IC ,over a  long period of time ,it produce the heat on the surface of the IC.Eventhough I got a good  output response form this IC .If  I use this IC continuously  the heat problem completely affect the IC of  functionality and it will lead to IC dead.

Hereby, I attached the my amplifer circuit for your reference.

Please suggest the good solution for this problem.

Thanks with Regards,
