Stereo 1.2W Audio Sub-System With 3D Enhancement

The LM4844 is an integrated Audio sub-system designed for stereo cell phone applications. Operating on a 3.3V supply, it combines a stereo speaker Amplifier delivering 495mW per channel into an 8& load and a stereo OCL Headphone Amplifier delivering 33mW per channel into a 32& load.
It integrates the Audio Amplifiers Volume Control mixer, Power Management control, and National 3D enhancement all into a single package. In addition, the LM4844 routes and mixes the stereo and mono inputs into 10 distinct output modes. The LM4844 is controlled through an I 2C compatible Interface
Boomer Audio Power Amplifiers are designed specifically to provide high quality output power with a minimal amount of external components.
The LM4844 is available in a very small 2.5mm x 2.9mm 30-bump micro SMD (TL) package.
