Abstract
In a case where potential of the first input terminal is lower than that of the second input terminal by an amount of the offset voltage, in a normal operation mode, the control circuit controls the polarity switching circuit so as to input the first contact voltage of the first contact to the first input terminal and input the control voltage to the second input terminal. On the other hand, in a case where the potential of the first input terminal is higher than that of the second input terminal by an amount of the offset voltage, in the normal operation mode, the control circuit controls the polarity switching circuit so as to input the first contact voltage at the first contact to the second input terminal, input the control voltage to the first input terminal, and invert the polarity of the amplified signal.
