A class D amplifier operates by deriving a two-state signal from a continuous control signal and amplifying it using power switches. At the core of every class D amplifier is at least one comparator and one switching power stage. In all but the lowest-cost power amplifiers, a passive LC filter is added. Here’s a summary of the benefits and disadvantages of the Class …

On the whole, Class D Amplifiers not only deliver high-quality sound but are also very energy efficient. The Bad. In the past, Class D Amplifiers produced a hard flat sound. The clarity of the sound is slightly less crisp than the larger amplifiers, but not enough for a “lay person” to discern a large difference.

Class D Amplifier •Class D amplifier employs MOSFETs which are either ON or OFF state. Therefore ideally 100% efficiency can be achieved. •PWM technique is used to express analog audio signals with ON or OFF states in output devices. •A loss in the switching device caused by 1)finite transition speed, 2)ON state resistance and 3)gate charge. +VCC
