<P>PROBLEM TO BE SOLVED: To provide a D/A conversion device capable of setting an output voltage with high resolution by a plurality of D/A conversion devices having low resolution. Ž<P>SOLUTION: The D/A conversion device includes the plurality of D/A conversion devices to which respective different output voltage ranges have been set, and a computing unit for adding or subtracting the output voltages of the D/A conversion devices. Also, the D/A conversion device includes the plurality of D/A conversion devices to which respective different output voltage ranges have been set, and a computing unit that has the output voltages of the D/A conversion devices input via an amplifier and adds or subtracts them.
