A low amplitude differential output circuit includes a pre-buffer circuit configured to output a main buffer drive signal of a-first drive signal and a second drive signal which are complimentary signals, as a differential signal; and a main buffer circuit connected with the pre-buffer circuit to output a differential output signal in response to the main buffer drive signal. Each of the first drive signal and the second drive signal has an amplitude between a first voltage and a second voltage, and the first drive signal and the second drive signal take a same voltage between the first voltage and a middle voltage between the first voltage and the second voltage.
