Hi...

I designed the amplifier circuit with the gain of 10 using AD811.while amplification this IC produces the heating effect if I use this IC for a long period of time IC becoming a too hot.I couldn't find the reason for this .
I need solution for this .Please suggest the ideas for this probelm.



With thanks,

Hello,

Without a schematic, we can not tell you what the cause is of the heating.
Please post a schematic.

You don't give as enough information. So we are unable to help you.
But I suspect that you have a problem with parasitic oscillation.
