My customers are considering ADA 4817-1.
So I got a question.It is about operation in the Power Down state.
#1 Is the input pin High-Z (high impedance)?
#2 Does the current leak from the input pin?
ADA4817 would work but it requires a minimum Vs=5V. The closest fit for your application is LTC6268. Let me know if this works. Also, could you share what your application is?
可以考虑一下 ADA4817-1， 带宽1,05GHz
My customers are considering using ADA 4817-1.
So I got a question.
Does the input impedance vary with frequency?
If it changes, how will it change?
I use ADA4817-1 to convert differential voltage to single end. The common voltage is +0.3V ~ +0.7V, and the differential voltage is about 5mV to 2000mV. The source impedance is about 5k ~10k Ohm. Signal frequency from DC to100MHz.
The simple circuit…
Do you mean Ada4817-1? Yes, it is possible. Look at http://welecw2000a.sourceforge.net/docs/Hardware/Aktiver_Tastkopf_mit_OPA659.pdf
ada4817 can replace opa659 there.

I use ada4817-1 and adg1414bcpz to convert current to voltage.
But the amplifier self-oscillate at frequency about 80MHz.
How can i cancel the unexpected frequency?
In attchment, ADA4817-1 convert current in DUT to voltage. ADG1414BCPZ used to…
Basically you may build a simple oscillator with a high frequency & high slew-rate Op-AMP like a ADA4817-1
TanQ for ur reply
before your answer, I did some simulations by spice models of two AD8067 in series and a composite of a AD8067 and a AD8009 and found improvements by composite configuration against two series amps.
now I have an another question…
