REF102: Nanoampere current source

Arivalagan Arivu

Part Number: REF102

I want to design a precision current source suitable to produce a current in the range of about 0.1 nA to 1 nA.

Can I do it with the REF102 voltage reference IC?

Or is there any suitable IC that I can achieve my goal.

Regards

Hi Arivalagan,

Let me get a reference expert to answer this for you, we have a range of precision references but I am not sure of currents that small.

Thanks,
Abhinav.

Hi Ar M,

How much headroom do you need on your current sink?

what kind of accuracy are you looking for?

Hi Ar M,

Have you had a chance to look into the requirements?
