A piezo driver system including a driver including a switching amplifier coupling a power port to a driver port, a battery coupled to the power port, a piezo device coupled to the driver port, where the switching amplifier provides a filtered driver signal to the driver port and returns stored charge from the piezo device to the battery. A method for driving a piezo device includes multiplying an input signal by an oscillator signal to provide a control signal, controlling a switching amplifier in accordance with the control signal to provided a filtered alternating current (AC) driver signal and a returned charge direct current (DC) signal, applying the filtered driver signal to a piezo device, and returning stored charge of the piezo device to a battery.
