A driver includes an output circuit which converts an input signal to a predetermined output waveform and outputs the predetermined waveform to first and second output terminals, a first output resistor having one end connected to the first output terminal, a second output resistor having one end connected to the second output terminal, an output resistor switch element having one end connected to the other end of the first output resistor, and having the other end connected to the other end of the second output resistor, and a 2-input-2-output amplifier which receives first and second input voltages corresponding to voltages at both ends of the output resistor switch element, and outputs voltages, which are produced by amplifying voltage differences between a reference voltage and the first and second input voltages, a high impedance state being set between both ends of the output resistor switch element.
