Class D Motor-Speed Control
Abstract: Class D audio amplifiers provide a dual benefit for battery-powered portable devices. They enhance
battery life, and they produce much less power dissipation than do their linear cousins. Those features make
the class D amplifier an ideal candidate for controlling speed and direction in small electric motors.
