ABSTRACT:
A power amplifier having at least one switched output stage and a control unit for determining drive data for the at least one switched output stage, the control unit including an encoder for encoding the drive data in order to generate a data signal (DAT) according to a serial data transmission protocol, a data transmission link is provided for the transmission of the data signal, and a modulator is provided for generating switching signals for the switched output stage or stages dependent on the data signal. The structural outlay for the power amplifier thus is reduced, particularly in the case of a power amplifier having a number of output stages.
