Freescales DSP5680x devices offer a combination of peripherals and software to enable Class D amplifiers to work at peak performance.From the perspective of wasted power, the best amplifier operates in pure switching mode-Class D. Normally, the amplifier has efficiency higher than 90 percent, meaning over 90 percent of the power is delivered into the load. In fact, a Class D amplifier works as a power D/A converter and can be used to realize high output power, 300W or more. The Class D amplifier is based on an analog technique of pulse width modulation (PWM).
