DIGITAL-TO-ANALOG CONVERTING SYSTEM

摘要

A digital-to-analog converting system for converting a digital code having higher order bits and lower order bits to an analog value comprising: a divider for dividing input digital codes into higher order bits and lower order bits; a first digital-to-analog converter for converting the higher order bits to a higher analog value in a first converting style; a second digital-to-analog converter for converting the lower order hits to a lower analog value in a second converting style which is inferior to the first converting style in linearity; and an adder for adding together the higher and lower analog values.
