摘要： A class D power output stage for switching a supply voltage comprises a limiting transistor with a controllable path and a control terminal, a complementary limiting transistor with a controllable path and a control terminal, a switching transistor with a controllable path and a control terminal, and a complementary switching transistor with a controllable path and a control terminal. A switched output signal between the controllable paths of the limiting and complementary limiting transistors can be taped off, the controllable paths of the limiting and the complementary limiting transistors are connected together and are connected to a first and a second supply terminal via the controllable paths of the switching and complementary switching transistors, and the switching and the complementary switching transistors have a lower electrical strength than the limiting and complementary limiting transistors. The output stage further comprises a level matching device for generating control signals in response to an input switching signal. The matching device is connected to the supply voltage and the control signals are fed to the control terminals.
