    Hello everyone:
    I would like to ask you, how is it possible to change an input voltage 5 DCV into a output voltage +/- 5 DCV.
    Thank you for your response.

    Use an oscillator and a CMOS switch array.

    There are chips which will produce -5V from a +5V supply. I have never used one.
    It all depends on what power you want.

    What duke37 said!

    In order to give a sensible (i.e. useful) answer, we need to know the power (or current) required from the -5V supply.

    Knowing the source of the 5V may also help us.
