摘要：
One or more input capacitors are connected to an inverting input terminal of an operational amplifier. Connected to the respective input capacitors are switches for on-off control of the input of an input signal, switches for on-off control of the input of another input signal, switches for on-off control of the input of a higher reference voltage and switches for on-off control of the input of a lower reference voltage. The switches for on-off control of the input of an input signal and the switches for on-off control of the input of another input signal are controlled by independent control signals.
