MAX9879 Stereo Class D Audio Subsystem

Maxim semiconductor introduces the MAX9879 Stereo Class D Audio Subsystem with DirectDrive Headphone Amplifier .The MAX9879 combines a high-efficiency stereo Class D audio power amplifier with a stereo capacitor-less bDirectDrive® headphone amplifier. Maxim’s class D amplifiers with active emissions limiting technology provide Class AB performance with Class D efficiency.

The Class D power amplifier delivers up to 715mW from a 3.7V supply into an 8Ω load with 88% efficiency to extend battery life.
The headphone amplifier of the MAX9879 delivers up to 58mW from a 3.7V supply into a 16Ω impedance load.
The MAX9879 Stereo Class D Audio Subsystem  is ideal for use in portable audio players , cellphones and other portable applications  .
The IC require few external components and low supply voltage an it has many features like :
Low RF Susceptibility Design Rejects TDMA Noise from GSM Radios , Input Mixer with User Defined Input Mode , Stereo 715mW Speaker Output (RL = 8Ω, VDD = 3.7V) , Stereo 58mW Headphone Output (16Ω, VDD = 3.7V) , Low 0.04% THD+N at 1kHz (Class D Power Amplifier) , Low 0.018% THD+N at 1kHz (Headphone Amplifier) , 88% Efficiency (RL = 8Ω, POUT = 750mW), I2C Control , Hardware and Software Shutdown Mode ,  Current and Thermal Protection
