PURPOSE:To improve the response to the application of a power supply, by connecting a load between output terminals of a pair of amplifiers in which the respective output signal of a signal source circuit is applied to the input. CONSTITUTION:Since a positive half wave output signal V01 to be amplified is outputted to a (10) terminal when a positive half wave signal Vi1 is applied, a load RL is driven with the amplified positive half wave output signal V01. When a negative half wave signal Vi2 is applied, since an amplified negative half wave output signal V02 is outputted from a (7) terminal, although a neutral point DC voltage is outputted to the (10) terminal, the load RL is driven with the amplified negative half wave output signal V02. Since the load RL is driven with the differential amplifying output signal by Amp1, Amp2, an audio output signal synthesized can be obtained from the load RL. |
