Abstract
An output amplifier which includes a drive voltage generating unit that generates a positive drive voltage and a negative drive voltage corresponding to a difference between an input voltage and an output voltage, an output unit including a first transistor and a second transistor forming a complementary output between a positive power supply terminal and a negative power supply terminal, the first transistor flowing out the current from the positive power supply terminal to the output terminal corresponding to the positive drive voltage, and the second transistor flowing the current from the output terminal into the negative power supply terminal corresponding to the negative drive voltage, and clamp voltage generating circuits that apply a positive clamp voltage corresponding to the input voltage to the positive power supply terminal and apply a negative clamp voltage corresponding to the input voltage to the negative power supply terminal.
