Looking at the data sheets the OPA445 is 45V and the other 44V. Only I thought I ordered 10 OPA455 but wrote the wrong part number down which was...

    0-30V Stabilized Power Supply

    Thanks Red wire, I did look for this the other might and wondered what happened to it, Does anyboady have the version for the OPA445 op-amp they have come back in stock at RS and ordered 10 of them so that I can continue with my version. Not sure if the above will work the same ? Thanks
