Abstract
In an operational amplifying circuit, the first transistor is configured to turn on and off according to an output signal outputted from the operational amplifier through the output terminal thereof. The second transistor is connected to the first transistor in series and configured to turn off and on reversely with the on and off operation of the first transistor on the output signal from the operational amplifier. The current control unit is electrically connected to the first and second transistors and configured to detect a current flowing in one of the first and second transistors. The current control circuit is configured to cause a current to flow into the control terminal of the one of the first and second transistors and to make other of the first and second transistors turn off.
