PROBLEM TO BE SOLVED: To provide a digital-to-analog converter which converts a digital signal to an analog voltage. SOLUTION: The digital-to-analog converter comprises a first row of resistors, a first group of switches arranged in cascade connection, a second row of resistors, and a second group of switches arranged in cascade connection, and the first row of resistors is electrically connected between a first voltage and an output terminal in the digital-to-analog converter. The first group of switches arranged in cascade connection has first and second switches controlled by a digital signal. The second row of resistors have first and second matching resistors electrically connected between a second voltage and the output terminal in the digital-to-analog converter. The second switches arranged in cascade connection include first and second matching switches controlled by an inverted signal of the digital signal. The digital-to-analog converter outputs an analog voltage through an output terminal. COPYRIGHT: (C)2009,JPO&INPIT
