Current Noise Beyond 1MHz

I would like ask for noise specification for ADA4895.

Input current noise in datasheet rev A. in FIG.24 is only to 1MHz.

Is possible to get wider frequency range for current noise(10MHz), like  input
voltage noise in graph FIG. 21?


For G=10 there is still a peak in the voltage noise as you can see from the
blue trace below.

For G=40 and G=100 the voltage noise peak is very small. There is no current
noise peak.

Rg=10 in all cases.
