Abstract

PURPOSE:To obtain a device which is not affected by the difference of the common mode potential of each input signal, by connecting the terminal of a floating ground FG of a differential amplifier to the shield terminal of a corresponding input signal. CONSTITUTION:Terminals of floating ground FG of differential amplifires are connected to shield terminals of corresponding input signals respectively. For example, input signals V1-Vn are inputted to differential amplifiers A1-An through signal input switches S11, S12,...Sn1, and Sn2, and output signals are inputted to an insulating amplifier A0 through signal output switches S1-Sn respectively to send an output signal V0. Terminals of floating ground FG of differential amplifiers A1-An are connected to shield terminals G1-Gn of corresponding input signals V1-Vn to prevent the influence of common mode potential of input signals upon one another.
