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.
