Hi,
I need an op-amp to drive 30mA, on 24V supply, signal is quite high frequency, 120kHz so I reckon I want at least 40dB to give low distortion, i.e. at least GBW 20MHz but 200MHz would be better. I also need to be able to turn the output high impedance.
Is there such an op-amp? And is it cheap?
TIA
