Hello,
I am trying to build an amplifier for quite a wide range of frequencies (40Hz - 200 kHz). I wanted to use OP467 since it has quite a wide bandwidth. So, using one section of OP467, I built an inverting amplifier with a gain of 10. However, I am starting to observe a decline in gain at about 40 kHz. At 100 kHz, the attenuation of gain is about 60%. Is there anything that I am missing or these results are reasonable?
Thanks,
Anton.
