DESCRIPTION  
APPLICATIONS  
The LM4859 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 8Ω load and a stereo headphone amplifier  
delivering 33mW per channel into a 32Ω load. It  
integrates the audio amplifiers, volume control, mixer,  
power management control, and Texas Instruments  
3D enhancement all into a single package. In  
addition, the LM4859 routes and mixes the stereo  
and mono inputs into 10 distinct output modes. The  
LM4859 is controlled through an I2C compatible  
interface. Other features include an ultra-low current  
shutdown mode and thermal shutdown protection.
