| what i try to achieve is that i also have a 0V to 10V range at the output of the circuit i thought that that could be done by adjusting the ref V and /or the gain factor in the first posted circuit Robert-Jan | |

In that case use +12V to power the LM358 in the 1st circuit diagram and change the Vref from +2.5V to +5V. This will give for a 0v to +10v input, a +10v to 0v output. OK.?

| New diagram still says 5-0v output...I assume that just didn't get changed? It is actually 10-0v correct? | |

 Remember: for a +10V thru 0V output, the LM358 will require a supply voltage of +12V. The Vref will have to be changed from +2.5V to +5V. OK?
