General Description  
Key Specifications  
The LM4934 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 520mW per  
channel into an 8Ω load, a stereo headphone amplifier de-  
livering 36mW per channel into a 32Ω load, a mono earpiece  
amplifier delivering 55mW into a 32Ω load, and a line output  
for an external powered handsfree speaker. It integrates the  
audio amplifiers, volume control, mixer, power management  
control, and National 3D enhancement all into a single pack-  
age. In addition, the LM4934 routes and mixes the stereo  
and mono inputs into multiple distinct output modes. The  
LM4934 features an I2S serial interface for full range audio  
and an I2C/SPI compatible interface for control.
