ABSTRACT:
An amplifier with power supply switching is arranged so that the levels of the power supply voltages to be supplied to the amplifying elements of the output stage are switched over in accordance with the level and the rise time of a signal corresponding to an input signal of the amplifier, thereby, to enhance the power efficiency and to prevent an increase of distortion, as well as to reduce switching noises which tend to occur during the switching of the power supply voltages.
