Abstract

There is provided a mute control circuit which is simplified to efficiently remove switching noise during the muting of each output and reducing the number of connection pins required for a given integrated circuit. The mute control circuit includes a pulse generator for receiving the each mute signal and generating a control pulse; a charge/discharge signal generator for receiving the control pulse and generating a charge/discharge signal and a switching control signal; a controller for receiving the charge/discharge signal and controlling the mute operation of the output terminal according to the switching control signal; and a switching signal generator for receiving the mute signal, generating a switching signal according to the switching control signal of the charge/discharge signal generator, and supplying the switching signal to the controller.
