Abstract
An audio amplification circuit comprises an amplifier having an input and an output, as well as an audio output to which a load can be connected. It additionally comprises a first driver stage having an input and an output which is not coupled to the audio output, and a second driver stage having an input and an output which is coupled to the audio output. The output from the amplifier is selectively coupled to the input of the first driver stage in a first phase of operation and then selectively to the input of the second driver stage in a second phase of operation following the first phase of operation.
