I am looking for information on current noise density for ADA4610, on parametric search it is listed as 1fA/(hz)^.5 but i see no reference in the datasheet for that value. I assume the 1fA is a default value when one isn't listed or can I trust that value to be accurate?
Here is the current noise plot of ADA4610.
Thanks for providing this information, but can you please double check it? The 1/f noise should be dominating in the low frequency region, as happens for the voltage noise density on non-internally chopped devices, and not in the high frequency region. Thanks in advance.
The FET input opamps like ADA4610 has almost no 1/f content unlike bipolar input opamps.
