ABSTRACT:
A digital-analog converter wherein reference voltage is divided by a first string-like resistor array, whose two adjacent outputs are selected by a first switch array depending upon the contents of upper bits of a digital signal and applied to the both ends of a second string-like resistor array, and one of switches in a second switch array is selectively turned on responsive to the contents of lower bits of said digital signal to pick up one of the divided voltages of said second resistor array.
