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?
It's not in the datasheet and it's seems a default value, but let me see if I could get some plot or data for it.
I'll get back to you.
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.
