PROBLEM TO BE SOLVED: To provide a switching amplifier adaptable to a digital input which is reduced in power consumption and circuit area. SOLUTION: The switching amplifier 10 is configured so that the output of a DAC 12 is directly transmitted to the switching amplifier 13 adaptable to an analog input, and the signal transfer function between an input and an output becomes the characteristic of a low pass filter.
