ABSTRACT:
The R-2R type D/A converter comprises an R-2R type D/A converter circuit provided with first and second series circuits each comprising a resistor and a switch. The first series circuit is connected between one end of a ladder resistor circuit and the ground. The second series circuit is connected between the other end of the ladder resistor circuit and the ground. The switches in the first and second series circuits are selectively turned on/off, so that an output signal may be supplied in either direction. First and second analog circuits are connected one to each terminal of the R-2R type D/A converter circuit. By turning on/off the switches of the first and second series circuits, a D/A converted output signal may be supplied selectively to the first or second analog circuit. Since the switches of the first and second series circuits are not located in the analog signal line, the D/A converted output signal can be supplied selectively to the two analog circuits, in a time-sequential manner, without adversely affecting an analog output signal of the R-2R type D/A converter circuit.
