Abstract
A digital-to-analog converter includes a group of resistors serially connected between a power source potential supply terminal and a reference potential supply terminal. First group switches are connected between a first circuit point and given serial connection nodes of the resistor group, and between the first circuit point and the reference potential supply terminal. Each of these switches is controlled so as to be selectively turned on according to the result obtained from decoding upper bits of a digital signal. Further, second group switches are connected between a second circuit point and other serial connection nodes of the resistor group, and between the second circuit point and the reference potential supply terminal. Each of these switches is controlled so as to be selectively turned on according to the result obtained from decoding lower bits of the digital signal. First and second capacitors are connected between an output terminal and the first circuit points, and between the output terminal and the second circuit point, respectively.
