Current mode and voltage mode combined digital analog converter

The invention discloses a current mode and voltage mode combined digital-to-analog converter. The digital-to-analog converter is composed of a current mode sub-digital-to-analog converter, a voltage mode sub-digital-to-analog converter, a current and voltage adder circuit and other modules, wherein the current mode sub-digital-to-analog converter is used for converting the most significant bit (MSB) representation of output numbers to a first analog output current, the voltage mode sub-digital-to-analog converter is used for converting the least significant bit (LSB) representation of the output numbers to a second analog output voltage, the current and voltage adder circuit is used for adding the first analog output current and the second analog output voltage to generate analog voltage output. The current mode and voltage mode combined digital-to-analog converter has the advantage that conversion from digital signals to the analog voltage is achieved on the condition that power consumption is low.
