My customer seeks to measure input current down to 1pA with this amp. I just reviewed this discussion:

So is this amp not suitable for measuring down to 1pA input current? Please advise when you can - thanks.
I moved your question about the ADL5304 in the RF Community. Someone here should be able to assist you.
Like i mentioned in the other post, it really depends on the customer's error requirements. If you have a limited operational temperature range (0 to 50 degrees C) and can accept 1-2 dB of error at 1pA, then I would say it is suitable at 1 pA input current. However, if you need a larger temp range and/or less error, then it probably will not work for you. I would advise studying the Typical Performance Characteristic plots that start on page 7.
