GaN FETs and ICs are gaining popularity in Class-D audio applications due to their ability to deliver high-quality sound with exceptional efficiency. Their fast-switching speeds enable precise pulse-width modulation, reproducing audio signals accurately. GaN's reduced power losses and heat generation lead to energy-efficient amplifiers, minimizing the need for large heatsinks. This results in smaller, more compact audio systems with improved power efficiency and reduced heat dissipation, making GaN technology ideal for portable devices, home audio, and automotive audio systems where space and energy efficiency are critical, without compromising audio fidelity.
