ABSTRACT:
A D/A converter, which has two output terminals, produces an estimated analog voltage signal from one output terminal which is connected to a comparator. The comparator compares the estimated analog voltage signal with an input analog voltage signal fed from an analog voltage signal source, thereby to produce a signal which corresponds to the difference in the respective values of the two intput analog voltage signals. The estimated analog voltage signal is output from the other output terminal of the D/A converter, which is connected to a load. The D/A converter can produce the analog voltage signal at either output terminal thereof.
