ABSTRACT:
A chopper type switching circuit having first and second transmission paths adapted to transmit a predetermined input signal to respective output terminals. First and second switching elements are connected respectively between the mid points of the first transmission path and a reference voltage line. A group of resistors are series connected between the output terminals. Third and fourth switching elements are connected respectively between the series connection points of the group of resistors and the reference voltage line. The first and fourth switching elements and the second and third switching elements are controlled to be alternately rendered conductive and non-conductive.
