Abstract

PURPOSE:To achieve a device by which the cause of pop noise can be removed and which is circuit-integrated, by switching signals from one to another when the potential of two signal sources is almost equal through the use of a switching signal generating circuit. CONSTITUTION:A switching signal generating circuit consisting of an input stage circuit 4, a comparator 5 and a switching signal generating circuit 6, is used. When the potential of two signal sources inputted from intput terminals 1, 2 is almost equal, an analog switch 7 is switched according to the state of a switching instruction signal of a switch 9 is switched so that the input terminal 1 or 2 can be connected to an output terminal 8. Thus, the cause of pop noise due to a transient phenomenon caused by the potential difference of a switched signal source can be eliminated and a circuit ease in circuit integration can be achieved.
