Abstract
A digital-to-analog-converter is provided which allows a use to set the reference voltage as desired and therefore has improved flexibility. A more significant bit data conversion section converts more significant bit data of digital data into a more significant analog signal corresponding to the more significant bit data by using a reference voltage inputted from outside. A less significant bit data conversion section converts less significant bit data of the digital data into a less significant analog signal corresponding to the less significant bit data. A controller controls the less significant bit data conversion section in such a manner as to output the less significant analog signal according to the reference voltage. An adder adds the more significant analog signal and the less significant analog signal, thereby outputting an analog signal corresponding to the digital data.
