An audio amplifier with a negative DC/DC converter is provided. The audio amplifier receives VDD and VEE as power supply signals. The negative DC/DC converter is arranged to provide VEE from VDD, such that VEE is a negative voltage that is lower in magnitude than VDD. Accordingly, the power loss can be minimal with lower Vee, even though the audio power is increased. The audio amplifier further receives an audio input signal, and a reference voltage that is the arithmetic mean of VDD and VEE.
