Class D Audio Amplifier Market Drivers and Opportunities

Use of GaN Technology in Class D Audio Amplifiers to Favor the Market

Silicon MOSFET has been used as the de facto transistor device technology in the creation of Class-D amplifiers. GaN technology now makes it feasible to design a new generation of amplifiers that will lead to significant advancements in product performance and audio quality. Silicon MOSFETs' fast switching limits the audio performance options available to designers. GaN transistors have a substantially higher operating frequency, enabling smooth, quick switching transitions. As a result, GaN Class-D audio systems include smaller, more effective audio devices with noticeably better audio performance. The application of GaN technology in Class-D audio design will make it possible for designers to produce a new wave of inventive products with enhanced energy economy and better audio performance in new, smaller form factors at cost-effective pricing.

Expansion of Automotive Industry
