ADL5303 EMI

Hello,

I want to detect the output current of a photo diode over a wide range; from 0.1 mA to 10 nA and below in industrial enviroment

To do this, I use the ADL5303 in following circuit:

The photo diode is connecting with a coax cable with shield on GND.

My big problem is the very bad EMI performace against HF-interfereces, because the signal to INPT-pin is very sensitve.

What can I do to to increase the rebustnes against HF-interferences?
