Abstract
PURPOSE:To prevent an analog conversion output within a stationary variation range based upon discontinuity from becoming discontinuously by varying a data value which shifts up or down in digit between its high-order and low-order bit groups and correcting digital data by an increment or decrement generated by the inversion of a preliminary bit. CONSTITUTION:At least one low-order bit of a high-order D/A converter 3 is set as the preliminary bit 5 overlapping with a high-order bit of a low-order D/A converter 4 and when the variation range of the digital data is a range wherein the data is shifted up or down in digit between both bit groups, a data value corresponding to a part where discontinuity is caused owing to the inversion of the preliminary bit 5 is shifted by the preliminary bit. The increment or decrement of the digital data due to the inversion of the preliminary bit 5 is corrected before analog conversion, so the analog conversion output is prevented from becoming discontinuous.
