Patent abstract
A Provided is a differential amplifier in which a current flowing into an output transistor may be adjusted to a constant value even when a voltage of a non-inverting input terminal changes. A current flowing through the differential amplifier circuit is controlled by a current source, a current value of which is changed depending on the voltage of the non-inverting input terminal.
