Companions unveil GaN audio amp reference design

GaN Methods and Axign have developed a 1000-W Class-D GaN audio amplifier to allow smaller, extra environment friendly, and extra highly effective audio techniques. Geared toward automotive, skilled, and prosumer audio purposes, the reference design will assist audio designers remedy a number of technical challenges, reminiscent of effectivity and warmth technology in high-power audio amplifiers.

Demonstrated at CES 2023, the GaN-based audio amplifier eliminates the necessity for heatsinks, leading to low working temperatures. This permits designs that meet the necessities of demanding purposes, reminiscent of high-end techniques working with high-resolution audio sources and delivering enhanced sound high quality with excessive energy.

Key options of the 1000-W Class-D GaN audio amplifier embrace:

  • 2 × 500 W/2 Ω at 50 V or 4 Ω at 70 V (bridge tied load) with 97% effectivity
  • 1 × 1000 W/1 Ω at 50 V or 2 Ω ato 70 V (parallel bridge tied load) with 98% effectivity
  • Lower than 3 W of whole idle losses for the GaN energy levels and LC output filters

Different efficiency traits embrace post-filter suggestions, 50-V and 70-V output functionality, 70% reductions in idle losses, and 50% discount in energy loss.

A datasheet for the 1000-W Class-D GaN audio amplifier reference design was not obtainable on the time of this announcement.
