What is the current noise of the AD8630 at 1kHz

The current noise spec is 5fA per root Hz at 10Hz and I can't find any information for higher frequencies.

The application is a wide band magnetic sensor with with a frequency range between 0.001Hz and 10kHz.  The ideal amplifier would have no 1/F noise, low voltage noise, and very low wide band current noise. The source is inductive so the current noise is only a critical parameter at higher frequencies. 

The combination of low voltage noise, no 1/F noise, and <20fA wideband current noise seems to be unobtainium with current technology. So I am assuming there is significantly more than 5fA per root Hz of current noise at higher frequencies. But I figured it couldn't hurt to ask before I attempt to measure it.
