    i have a problem where i have a voltage that ranges from 0-5v. i need to create a circuit that inverts that range.

    eg: where the output will be 5v when the input is 0v, output is 4v when the input is 1v, etc, until the output is 0v when the input is 5v.

    i'm thinking this is possible with an op-amp somehow, anyone have some ideas?

    i appreciate the help
