EVALUATION MODULE: GS-EVM-AUD-AMPOL1-GS

Turnkey Open Loop Digital Class-D Amplifier Module
This complete stand-alone 200-watt-per-channel Class-D amplifier module is designed for manufacturers of powered loudspeakers and stand-alone stereo and multi-channel amplifiers. GaN Systems GS-EVM-AUD-AMPOL1-GS is designed as two independent half-bridge outputs, for use in both stereo and single-channel applications. The GaN open loop approach provides an ideal switching form for Class D amplifiers. The high performance of switching signals delivers a dual feedback loop that provides better performance than a single loop / closed filter.
