Abstract
An integrated audio amplifier with combined regulation of the 'mute' and 'standby' functions and the switching transients, is configured so that the 'mute' and 'standby' states are compulsory transitional states between a state of normal operation and a cut-off state. The amplifier includes an amplifier circuit and three threshold comparators each having an input terminal connected to a common circuit node. The comparators regulate the biasing of the amplifier circuit and the transmission of signals therethrough in accordance with the common circuit node voltage.
