Digital to analog converter having low power consumption

摘要

A digital to analog converter having low power consumption is provided. The digital to analog converter includes a reference bias voltage generator and a conversion current generator. The reference bias voltage generator generates a predetermined bias voltage, and the conversion current generator includes a plurality of current generators and supplies current which correspond to the bias voltage and a plurality of digital signals to an output terminal. The current generators which correspond to activated digital signals of the plurality of digital signals among the plurality of current generators supply current to the output terminal, but the other current generators which correspond to deactivated digital signals of the plurality of digital signals do not supply current to the output terminal.
