using AD8067 as inverting amplifier

Hi,

I tried to work with AD8067 operational amplifier as inverting amplifier. My input resistance is 12k ohm and feedback resistance is 10k ohm. Now gain should be less than one. I tried to simulate it in LTspice with spice model of AD8067 from analog device website. I got very weird result. The frequency increased and the output is like a beam. I am attaching the circuit and output curve here. Can anyone please help me to solve this problem?

Thank you.

  • Hi Niloy,

    If I may add on my previous response, the AD8067 is stable at gains > 8. As for your application, i think AD8067 is not the best part for you.

    Can you share your schematic of your application so that I can assist you better? What are your input requirements if I may know? As what i understand, you want a gain of -0.826? At to what level do you expect your current output will be?

    Best Regards,
