摘要： A digital-to-analog converter includes: a resistor string; a plurality of first switches each connected between an output node and a corresponding one of first endmost, second endmost and intermediate nodes of the resistor string; a decoding unit adapted for converting a higher-order portion of a digital signal into a decoder signal used to control the first switches such that one of which is selected according to the higher-order portion to connect the corresponding one of the nodes to the output node; and first and second voltage-setting units adapted to be connected between one of first and second reference voltage sources and one of the first and second endmost nodes of the resistor string, and operable in response to a lower-order portion of the digital signal to adjust voltages at the first endmost, second endmost and intermediate nodes of the resistor string according to the lower-order portion of the digital signal.
