Abstract
A Class D amplifier system utilizing high voltage level shifting technology and an adaptive power supply which adjusts the magnitude of the output voltage based on audio input levels to reduce switching losses at low audio input levels. The amplifier system of the present invention also removes any DC offset at the output by providing an equal positive and negative power supply with respect to ground.
