Richardson RFPD, Inc., an Arrow Electronics company, announced today the availability and full design support capabilities for a new platform of evaluation boards for Class D audio systems from GaN Systems Inc.

GaN E-HEMT fast switching, low output capacitance (Coss), and zero reverse recovery charge (QRR) enable a new level of performance for Class D audio amplifiers. The new GS-EVB-AUD-xxx1-GS GaN-based evaluation board 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.

Key features of the 2-channel Class D amplifier include:

• Complete Class D amplifier
  • Multi audio signal inputs
  • Bridge-tied load output
  • Option to switch between open-loop and closed-loop designs with optimized DSP control of each configuration
• High-performance audio
  • 200 W/Ch (8 Ω), 300 W/Ch (4 Ω)
  • > 108 dB SNR and dynamic range
  • < 0.01% THD+N (8 Ω, 1 W)
  • +/- 0.5 dB frequency response (8 Ω)
• High-performance output
  • 96% efficiency
  • Reduced thermals

Key features of the companion switch mode power supply include:

• Complete audio LLC SMPS
  • Universal AC line input
  • Easy integration with GaN amplifier
  • Common-mode AC filter
• High-performance audio
  • 400 W continuous, 550 W peak
  • +/- 32 VDC dual-rail output
• High-performance output
  • No heatsinking, no cooling
  • High efficiency, 40% loss decrease
  • EMI/EMC friendly
