Abstract

PURPOSE: To maintain high resolution with excellent linearity by correcting errors of high order bit signal and combining low resolution D/A coverter.
CONSTITUTION: The input binary signal is divided into groups of high order bit MSB and low order bit LSB and each of them is added ADD through D/A converter DA1 and DA2, thus obtaining analogous signals of excellent linearity. In this case, the data corresponding to the error that occurs in DA1 is supplied to DA2 and the output of DA1 and that of DA2 are added.
