Hi,
I need help designing a circuit that is intended to drive a 30Vpp 10MHz AC output. I am attempting to use a basic non-inverting opamp setup with a closed-loop gain of 6 (can be easily adjusted) to amplify an input from a function generator. With my setup, the gain drops off at frequencies above 10kHz. This is nowhere near the frequency I need. At frequencies > 1MHz, there is no signal being read at all.
As I'm not too familiar with opamps, I'm not sure if I am missing something in the specifications of the opamp, or need to have something specific in my circuit setup? I tried to pick an opamp with a high Gain Bandwith product. Are there any opamps that can be recommended, or if there is a better (simple) way to produce such an output without an opamp?
The opamp I am using is the LT1365CN (link to data sheet).
Thanks for any help.
