The size reduction increases product design creativity, allowing the amplifier to be built into a speaker or other unit, such as set-top boxes and DVD players. A large boom box can be reduced to the size of a portable CD player and still deliver the same sound volume and quality. Increased efficiency also enables battery-powered amplifiers that can run up to three times as long compared to conventional amplifiers. Dead-time control in Class D amplifier power output stages minimizes harmonic distortion and provides the highest audio quality. IR's devices contribute to higher overall amplification efficiency.
More efficiency means less heat and reduces size and weight.
