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?
