Circuit help. I want a Voltage gain from 5 volts to 10 volts.

integrated-circuitoperational-amplifiervoltage

I need some circuit help.. I am trying to boost my voltage from a 5v source to a 10v output so I want a Gain of 2. I Ran the simulation and built the circuit exactly how it is shown in the figure below. I am using an op-amp 471CN and when I test the circuits output (Vout) I still only get a 5 volt output. I'm fairly new at this so can anyone help me with trying to figure out why i'm not getting 10 volt output. I'm sure it's simple but I just don't see it now. Thank you for your time.

You will need to supply the op amp with a voltage high enough to contain both the output and any headroom the op amp needs to operate in, so that would mean a supply of at least 11.5V or so.

If you do not have a supply high enough then you will need to use a boost regulator, charge pump, or voltage multiplier to increase the voltage instead.
