<p>The invention provides a D/A conversion circuit in which the polarities of a series of input digital data are reversed (1a) with every other data block, and the original digital data and the reversed digital data are alternately D/A converted (2). An output analog signal (f) is obtained by subtraction (6) between the two D/A converted analog signals (d, e). With the above-mentioned arrangement, the D/A conversion circuit has a dynamic range equivalent to that using two D/A converters even with a single D/A converter.</p> |
