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 Amplifier GaN Class D audio amplifier (Amp) GS-EVB-AUD-AMP1-GS Companion switch mode power supply (SMPS) GS-EVB-AUD-SMPS1-GS Bundle: Amp + SMPS GS-EVB-AUD-BUNDLE1-GS 4
