To perform a Noise-Analysis we need the Current Noise Density of the AD8648ARZ.
Unfortunately this value is not available from the datasheet.
-        Can you please help to provide this value?


The AD8648ARZ has a very low Input Bias Current (1pA). Therefore the part has
either a CMOS or FET input in which the current noise is going to be
insignificant compared to the voltage noise. This is also reason why it is not
