Title: Amplifier circuit
Inventor: TAKESHITA RITSUJI
IPC: H03G3/10
Filed: 1986-09-26
Abstract: PURPOSE:To reduce noises such as a pop sound by connecting a voltage holding circuit which operates in synchronism with the start of muting to the output terminal of a push-pull connected output circuit, and holding the voltage of the output terminal at specific voltage level at the start of muting. CONSTITUTION:When a mute switch S1 is closed, a voltage Vm divided by resistances R1 and R2 is obtained and a transistor (TR) Q1 turns on. A TR Q25 is driven with the output current I21 of a TR Q21 to turn on and cut off a constant current Is, so an amplifier 2 is turned off. The voltage level of a reference voltage Vref is set to 1/2 Vcc, so the base-collector voltage of a TR Q34 reaches Vref through the operation of TRs Q33 - Q36. Consequently, when muting operation is started, the output terminal of the output circuit 3 is held at 1/2 Vcc, and this voltage level is held by a voltage follower circuit 11 for the muting period.
