GaN Audio Class D Evaluation Boards
Fast switching, low Coss, and zero QRR Enhancement Mode GaN transistors enable a new level of performance for Class D Audio amplifiers. This GaN-based EVB platform provides an excellent reference design for implementing a high-performance, low-cost audio system. The Class D amplifier and companion power supply designs are optimized for sound quality, thermal performance, size, and cost.
