An input circuit has a differential amplification circuit which converts a differential signal to a single end signal to output the single end signal, an attenuation circuit which attenuates a first input signal to output the attenuated signal to the differential amplification circuit, a capacitor in which one end thereof is connected to a first input terminal to which the first input signal is inputted, and another end thereof is connected to an output side of the differential amplification circuit, a buffer to which the single end signal outputted from the differential amplification circuit and a signal transmitted through the capacitor are inputted, and which outputs the output signal, and a feedback circuit which outputs a signal based on an output signal outputted from the buffer and the second input signal to the differential amplification circuit.
