REF102: Nanoampere current source

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

Ar M

  • 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?
