Companies Unveil Revolutionary, High-Efficiency Class-D Amplifier At CES 2022

OTTAWA, ON AND LAS VEGAS, NV / ACCESSWIRE / January 6, 2022 / GaN Systems, the global leader in GaN power semiconductors and audio technology innovator Axign, debuted a new groundbreaking GaN-based 500W Class-D audio amplifier. This reference design merges best-in-class technologies, including GaN Systems' GaN power transistors and Axign's Class-D controller, enabling companies to create unique audio systems that are smaller, sleeker, more efficient, more powerful, and provide better audio quality than previous generations.

Axign and GaN Systems Develop Revolutionary 500W Class-D Audio Amplifier.

Both companies will be showcasing the demo board at CES. Under Axign's theme of "Listening to the Sound of Innovation," this solution signals the next leap in efficiency and sound quality performance as audio needs have evolved. This design is ideal for consumer and automotive audio applications, including active loudspeakers, television soundbars, audio entertainment solutions, and streaming audio amplifier solutions.

Key features of the 500W Class-D audio amplifier reference design:

Rated Output Power: 2x 250W in 4 Ohm BTL (optionally 1x 500W in 2 Ohm PBTL)
Frequency Response: 20Hz - 20kHz +/- 0.1dB, DC - 40kHz +/-3dB
High Dynamic Range: 109dB-A in BTL (optionally 118dB-A in PBTL)
Output Noise Voltage: 110uV A-weighted, 20kHz AES17 (optionally 41uV in PBTL)
Very low and flat THD: <0.01%, 20Hz - 20kHz
Damping factor: >4000

In addition to the key features, audio designers will love that the solution is hi-res audio compatible. The 500W Class-D audio amplifier reference design solves several technical challenges, especially heat generation in high-power audio amplifiers and efficiency. Designers will be able to:

Eliminate heatsinks.
Increase efficiency as GaN has lower switching and conduction losses and high-current capabilities.
Enhance sound quality (or reach a Class-A sound quality) with a post-filter feedback Class-D controller with full control over the loudspeaker.

"GaN-based audio amplifiers and accompanying power supplies are becoming the standard in audio systems, expanding possibilities in design and performance. This collaboration with Axign for the 500W Class-D audio amplifier encapsulates this evolution allowing the delivery of smaller, lighter, and better sounding audio systems," said Paul Wiener, GaN Systems' VP of Strategic Marketing.

Richard Langezaal, Axign's VP of Business Development, added, "Getting amazing sound quality and full control over the loudspeaker are just one of the many benefits of our 500W heatsinkless Class-D audio amplifier with GaN Systems. We are excited to shake up CES 2022 and the consumer audio market in displaying and demoing exciting audio technologies like these."
