ABSTRACT:
A driving voltage control device includes: a first differential amplifier circuit for receiving a first input voltage and outputting a first output voltage; a second differential amplifier circuit for receiving a second input voltage and outputting a second output voltage; a control section for selecting one of a first mode and a second mode; and an output section for supplying the first output voltage output from the first differential amplifier circuit to an output node when the first mode is selected by the control section and supplying the second output voltage output from the second differential amplifier circuit to the output node when the second mode is selected by the control section. When the first mode is selected, the control section increases a driving power of the first differential amplifier circuit.
