Tipping Point Achieved as GaN Technology Moves from Early Adoption to Mainstream Acceptance

High quality audio is now a “must have” across all segments from professional to home and portable applications. Class-D audio systems with GaN (gallium nitride) are not only smaller and lighter but provide better sound quality and were one of the technology trends in 2020. And because it’s that time of year to make predictions for the coming year, GaN Systems, a leading company in this space, published a forecast of 2021, identifying key trends for the technology.
