2 x 1.5W, Stereo Class D Audio Subsystem with DirectDrive Headphone Amplifier
General Description
The MAX9775/MAX9776 combine a high-efficiency Class D, stereo/mono audio power amplifier with a mono DirectDrive ® receiver amplifier and a stereo DirectDrive headphone amplifier.

Maxim's 3rd-generation, ultra-low-EMI, Class D audio power amplifiers provide Class AB performance with Class D efficiency. The MAX9775/MAX9776 deliver 1.5W per channel into a 4 load from a 5V supply and offer efficiencies up to 79%. Active emissions limiting circuitry and spread-spectrum modulation greatly reduce EMI, eliminating the need for output filtering found in traditional Class D devices. The MAX9775/MAX9776 utilize a fully differential architecture, a full-bridged output, and comprehensive clickand-pop suppression. A 3D stereo enhancement function allows the MAX9775 to widen the stereo sound field immersing the listener in a cleaner, richer sound experience than typically found in
