ABSTRACT:
According to the present invention, an operational amplifier apparatus for outputting to an output terminal a voltage corresponding to a difference between a voltage in a first input terminal and a voltage in a second input terminal is provided. The operational amplifier apparatus includes an operational amplifying section for outputting to the output terminal a voltage corresponding to (V2-V1), where V1 is the voltage in the first input terminal, V2 is the voltage in the second input terminal and k is a constant and a current supply section for supplying a current corresponding to the difference between the voltage in the first input terminal and the voltage in the second input terminal. In the operational amplifier apparatus, the current supply section supplies a current to at least one of a capacitor included in the operational amplifying section and the output terminal, thereby increasing a slew rate.
