A simple way to convert 0-20ma into 0-10volt

Could that be because they are really ancient and EOL'd?

Linnix,

I believe that John was merely pointing out in a nice, polite way that your posts are flawed with very basic misconceptions - not just a matter of small adjustments or component values. You should re-read John's posts in that light, and/or consult a tutorial on opamp circuit design. For this application, an inverting topology is wrong, and the rest just makes it wronger. If you really want to use an opamp (eg if a low-Z output is needed), and in the absence of any other information, a more logical way to do it is as a simple buffer, eg

You need only R2. Usually 0-20mA range is moved to 4-20mA or 2-10mA just to avoid line broke problems when the current is 0 not because of the signal but becouse of a circuit malfunction.
