摘要：PROBLEM TO BE SOLVED: To remove noises occurring at the time of raising andfalling a power source by feeding bias voltage, corresponding to a signal and a powersource and selecting one of a signal or a bias voltage in accordance with the state of thepower source for outputting. SOLUTION: A switch circuit 11 supplies the output signal ora bias voltage Vbias of an input amplifier 3 to output amplifiers 4, 5 in accordance withterminals Te1 and Tc2. When the switch signal of the terminal Tc1 is at a high level, the

switch signal of a terminal Tc2 comes to a low level and when the switch signal of theterminal Tc1 is at a low level, the switch signal of the terminal Tc2 becomes high level.The circuit 11 supplies the output signal of the amplifier 3 to the amplifiers 4, 5, when theswitch signal of the terminal Tc1 is at a high level and the switch signal of the terminal Tc2is at a low level, and the circuit 11 supplies the bias voltage Vbias to the amplifiers 4, 5,when the switch signal of the terminal Tc1 is at a low level and the switch signal of theterminal Tc2 is at high level.
