19-0746; Rev 4; 8/08 MAX9775/MAX9776 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 4Ω 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.
