Abstract:
1. D/A converter including n+1 (n is a natural number) capacitors in total consisting of one terminating capacitor (C 0 ) serving as a unit capacitor and n binary-weighted capacitors (C 1 - 4 ) that are subjected to binary weighting to the unit capacitor in the ratio of 1:2:4: . . . :2 (n−1) , and, an inverting amplifier (INV 1 ) for obtaining amplified output, the input terminal of the inverting amplifier being connected to first terminal side of the n+1 capacitors in common, further comprising: a feedback switching means (SWR a switching means for terminating operation (SWR a plurality of switching means for input operation (SWD
