    Hello i was wondering if anybody knows of an ic chip or has a circuit that could have 0-5v on the input and the voltage would control the output which would act like a potentiometer?

    This circuit goes by different names:

    transconductance amplifier
    variable gain amplifier
    analog multiplier

    You can do this with a FET.
