<p>A push-pull type output circuit comprises an input differential amplifier stage (11) responsive to an input differential voltage signal, and an output driver stage (12) for driving an external load, wherein the input differential amplifier stage and the output driver stage are implemented by a class AB amplifier circuit (11a/ 11b) and two current mirror circuits (12a/ 12b), respectively, so that the current utilization factor is improved. <IMAGE></p> |
