Abstract

PURPOSE:To reduce the switching noise which is caused by the parasitic capacity and the like contained in the output signal by using two units of the switching element of the same constitution and then compounding the output of the switching elements in the opposite phase to each other. CONSTITUTION:The 1st and 2nd switching circuit 13 and 14 which is turned on and off by the control signal given from control signal input terminal 15 are controlled to switch selectively the signals sent from input terminal 7 and 8 and to deliver them, and the input signal is transmitted or cut off. In such circuit, the signals of terminal 7 and 8 are branched off and applied to circuit 13 via non-inverse amplifier 9 and 11 to be then applied to circuit 14 via inverse amplifier 10 and 12. Then each output of circuit 13 and 14 is applied via input adjusting variable resistance RA and RD to the non-inverse and inverse input terminals of operational amplifier 16 respectively. At amplifier 16, the output of circuit 13 and 14 are compounded in the opposite phase each other, thus reducing the switching noise caused in the output signal.
