PROBLEM TO BE SOLVED: To reduce interference between two or more drive voltages applied to a load such as a CCD. SOLUTION: A drive circuit has a driving mode for outputting current from a certain reference current through current mirror circuits CM1, CM2 when two or more drive voltages are applied to the load such as a CCD, and the current is slowly switched at a certain optional time constant by time constant circuits 540, 541. Consequently, the transient speed of voltage Vout which is a drive voltage is decreased and the interference between the drive voltages is reduced. COPYRIGHT: (C)2007,JPO&INPIT
