Hi,
I'm desesperately searching for an amplifier to make an input impedance adapter.
My input signal is a DC to 200MHz sinusoidal voltage between 0 and 4.096V with an impedance of up to 1KOhm.
I would like to make a voltage follower but haven't found any reference that could sustain this frequency with this output voltage.
I would like to power my amplifier between +/- 5V or +6V/-5V.
My output load will have about 250 Ohm impedance.
Can you suggest me a reference or a typical circuit that could make my adaptation?
Thanks in advance,
Best regards,
Vincent DECAUX
