A drive current direction between first and second amplifiers can be selected using a received indication of an output current in an at least partially reactive load, and an amplified output signal can be produced using the selected drive current direction and the first and second amplifiers. Further, the first and second amplifiers can be configured to alternate between a pull-up mode and a pull-down mode, each amplifying half of a full wave output signal.
