The present invention relates to an amplifying circuit that can change load drivability responding to load conditions, and reduce power consumption. The amplifying circuit according to the present invention comprises an amplifying means that amplifies input signals a first time to generate a first and a second amplified signals through a first and a second transistors, and further amplifies the first and second amplified signals once again through a third and a fourth transistors, for final outputs; a detecting means for detecting the first and second amplified signals from the amplifying means and generating a first and a second detection signals; and a load drivability control means that is controlled by the first and second detection signals from the detecting means to change load drivability of the amplifying means.
