Title:
DA CONVERTER
Document Type and Number:
WIPO Patent Application WO/2002/080371
Kind Code:
A1
Abstract:
A DA converter has a unit assembly comprising 'n' units connected in series to a reference voltage and each composed of '2m' resistance members connected in series and '2m' switching members for connecting the resistance members to a common output end. The common output end of one selected unit of the unit assembly is connected to an output line through a switching member. 'n' switching members disposed in array positions corresponding to each other of the units are all closed by a common control signal at a time. Thus the lines for the control signals are few, and the circuit scale is small.
