ABSTRACT:
A D/A converter includes an analog voltage generating circuit for generating an analog voltage, and an offset-controllable amplifier amplifying the analog voltage with a predetermined amplification factor and outputting an analog output signal. An offset voltage generating circuit generates an offset voltage which is varied on the basis of a digital input signal. The offset voltage controls an offset of the offset-controllable amplifier.
