WANTED: Precision current source/sink

(1/2) > >>

Alex:
I am looking for a precision current source that can cover the nA and uA range. Sink capability would be ideal but not necessary. Output compliance can be as low as 10V in the first instance. Bandwidth is not important but if it can cover the audio range, that would be great.

I live in the UK and I don't want to break the bank. Please let me know if you have something suitable, all countries open.

Regards,
Alex

Does that mean you want to have an AC, not a DC current source? There aren't many, e.g. Keithley 6221.

If you want AC, consider robbing a bank.

Well even for DC powered one, without nA range,
you will have to crack down your credit card for good.

The word precision, is a very bad word in relation with cost.  ;D
And the point is that you are aware of it.

Alex,
You've not given a detailed specification. It might be possible to build this yourself.

Built what ?
An calibrator ?

I will bring the national TV and the press, if he did build something like that.   :)
