I need to use the ADL5304 to amplify the current of a photodiode.
I want to use the 200 dB range because I need to amplify very low light level.
I have a problem with Vlog, it is not linear between -90 and -66 dBm. I think this problem is due to the dark current of the photodiode but I can't find how to fix it.
Can you say how we can compensate the dark current of the photodiode using the evaluation board of ADL5304?
