Turnkey Closed Loop Analog Class-D Amplifier Module

This self-contained 200 watt-per-channel Class-D amplifier module is designed for manufacturers of powered loudspeakers and stand-alone stereo and multi-channel amplifiers. With the new GaN Systems GS-EVM-AUD-AMPCL1-GS a heat sink is not required under normal conditions. Thermal protection is provided for worst-case thermal environments, and 96% efficiency reduces heat and system size.
