摘要：
Disclosed is a Rail-to-Rail amplifier including a plurality of differential pairs of a first conductivity type and a plurality of differential amplifiers of a second conductivity type each with one of an input pair thereof constituting an input terminal, a differential amplifier that outputs an output voltage according to the range of provided supply voltage, a determination unit for determining whether to stop operations of the differential pairs of the first conductivity type or the second conductivity type according to a predetermined input signal, and a differential pair control unit for stopping the operations of the differential pairs of the first conductivity type or the second conductivity type according to the output signal of the determination unit.
