A common application for an operational amplifier is an inverting amplifier. This amplifier takes a positive voltage on the input, and produces a negative voltage with the same magnitude. In the same manner, the amplifier also makes negative voltages positive. A linear gain can be achieved by changing the resistor ratio in the feedback path.
