Gen2 GaN Audio Class D Amplifier Evaluation Board
Fast switching, low Coss, and zero QRR Enhancement Mode GaN transistors enable a new level of performance for Class D Audio amplifiers. The amplifier evaluation board provides a universal evaluation platform for Open-Loop and Closed-Loop configurations for measured and listening performance assessment and comparison. The Class-D output stage of the audio amplifier is implemented with 100V GaN enhancement mode HEMT (E-HEMT) devices.
