Abstract: <P>PROBLEM TO BE SOLVED: To reduce the quantization noise without increasing the circuit scale.  <P>SOLUTION: A ground level is set to an operational amplifier configuring an integrator 13 in place of an analog input signal Vi on the basis of a conversion period signal ADEN reaching a HIGH level for a prescribed period around an upper/lower peak level of a triangle wave for generating a voltage command signal, when the conversion period signal ADEN is at a HIGH level, the analog input signal Vi is fed to the operational amplifier 25, and when the conversion period signal ADEN is at a LOW level, the ground level is fed to the operational amplifier 25.
