increasing gain of ad8000 amplifier
Hi,
I'm trying to build a non-inverting gain circuit using one of several possible op-amps (Analog AD8000, National LMH6702, LMH6703).
I am following the manufacturers recommended design, but having the same problem with all 3 chips. My output is dropping sharply and reversing phase at about 45MHz.
I know this is a pretty specific question, but maybe someone here has dealt with the same problem...I am totally new to this and don't have any ideas.
I've attached a schematic of my circuit and a Bode plot to anyone who might be able to help.
Thanks!
