OpAmp (ADA4522) heating issue

I am using this ADA4522 as voltage follower which is supplied with +35V and -5V. When input signal with below specs is given the OpAmp is heating
Input signal specs:
20Vpk, 5us rise/fall time and 2us high/low time.

  • Hi,

    Just a couple of questions about your setup:

    1. When you configured the ADA4522 in a voltage follower, is there a feedback resistor?

    2. Is there a source resistance or input resistance connected to the non-inverting input? If so, what's the value?

    Thanks,

    Donnie

    Thanks for the reply

    No there is no feedback resistor

    2. Is there a source resistance or input resistance connected to the non-inverting input? If so, what's the value?

    Yes we have connected 2 Ohm resistor

    Thanks
