Part Number: OPA172
Could you kindly help to give some advise?
Form the below picture when OPA172 is in a constant current source circuit and under the situation of adjustment end is invariant, is the maximum current changing with the change of temperature or current of the constant current source?
Thanks a lot!

In reply to Ron Michallick:
In addition to Ron's comments, as long as the current source is operating in a linear operating region for the op amp then the current will not change very much with temperature. There will be small changes in output current vs. temperature due to changes in the input offset voltage of the op amp vs. temperature but these changes are likely smaller than you are concerned about.
