If I can believe the simulation (a big if) the ADA4899-1 can provide 90 dB
isolation at 10 MHz, rolling up to 70 dB at 100 MHz, when configured with a
gain of +2
The subcircuit model provided by ADI is useless for noise, unfortunately. I
guess I'll have to build and measure, which I don't mind doing. Unless
it turns out to be a waste of time, and I should have just used the transistor
circuit.
