ABSTRACT:
A digital-to-analog converter includes a generator responsive to a digital input signal, a set of switches each being directly connected to the generator, and a first and a second terminals connecting therebetween a resistor device having a plurality of nodes directly connected to the switches in order that a node voltage can be obtained between one of the nodes and one of the terminals to serve as an analog signal. Such converter has a low distortion
oise and can be used in a broad source voltage scope.
