GaN E-HEMT fast switching, low Coss, and zero Qrr enables 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 are optimized for sound quality, thermal performance, size,
and cost.
Features and Benefits
•Superior sound quality through reduced THD and increased bandwidth
•High efficiency due to lower transistor switching and conduction losses
•Reduced size and weight from high switching frequencies
•Low cost implementation through simplified design
•Low EMI/EMC due to high performance switching
•2 channel, BTL amplifier designed for configurability and scalability
•Scalable 75-500W companion split rail PSU optimized for use with
