摘要： While a charge pump activation/deactivation control circuit is outputting a high level signal, MOS transistors for short-circuiting a flying capacitor are off, and the charge pump circuit operates normally. When the charge pump activation/deactivation control circuit outputs a low level signal, the MOS transistors for short-circuiting the flying capacitor are turned on, and the charge pump circuit is deactivated. Consequently, the voltages at the terminals of the flying capacitor are the same and the charge charged therein is discharged. Therefore, when the charge pump circuit is activated again, the initial amount of charge charged to the flying capacitor is zero. Consequently, no large current flows through an output capacitor in the first discharging cycle after the re-activation.

摘要： A muting circuit of the present invention includes: an input terminal that receives a control signal for allowing switching between ON and OFF of a mute operation; and a muting transistor connected to the input terminal and an output terminal of the amplifier. The muting transistor is a MOS transistor, and a gate is connected to the input terminal, a drain is connected to the output terminal of the amplifier, and a source is grounded. Consequently, a shot noise due to a DC difference caused when a mute state is switched between ON and OFF can be suppressed.
