ABSTRACT:
An asynchronous signal processing circuit device having an A-D converter and a D-A converter in which a single ladder voltage generating circuit is commonly or jointly used by changing over a multiplexer during both the A-D and the D-A conversion processing. The asynchronous signal processing circuit device according to the present invention further comprises an interrupt signal generating circuit which produces an inhibit signal so as to provide a predetermined inhibit period during which the interruption by the second signal processing circuit to the first signal processing circuit is inhibited, thus preventing a misoperation of the asynchronous signal processing circuit device at the time of switching over the converters.
