'Input Bias Current Drift Distribution' ADA4806

Hi Yoshinari,

I will check whether that information is available and get back to you.

May I ask why this you need this information? What is your application?

Thanks!

Kris

Thanks your response.

This is current measurement applications.

Thank you.

I will check into the characterization data and see what is available.  If there is some data it will likely be from a limited sample size and may not produce a typical gaussian looking histogram.

I found some characterization data for ADA4805/6 Ibias vs temp and have attached the histogram.  The sample size is only 30 pieces so the shape isn't exactly gaussian but it should be enough to give you an idea what to expect.  Also, the data was taken at the temperature endpoints (-40 and +125) and the Ibias vs temp curve is not exactly linear so the drift will vary slightly depending on which portion of the temperature range you're looking at.  As far as I can tell this is all the temp data we have on this.

Thank you so mach.
