Abstract
In a power amplifier having multiple, switched output stages and a driver, and method for driving the switched output stages, a number of drive signal groups are generated for respectively driving the switched output stages. A number of pattern signal groups are generated dependent on at least one input signal, and drive signal groups are generated from the pattern signal groups, with each pattern signal group being allocated respectively to one of the switched output stages, and this allocation is changed in segments. A good load balancing between the individual switched output stages is achieved with a low circuit-oriented outlay.
