LM4855  
Integrated Audio Amplifier System  
General Description  
Key Specifications  
n THD+N at 1kHz, 1.1W into 8BTL  
n THD+N at 1kHz, 115mW into 32BTL  
n Single Supply Operation  
1.0% (typ)  
0.5% (typ)  
2.6 to 5.0V  
The LM4855 is an audio power amplifier system capable of  
delivering 1.1W (typ) of continuous average power into a  
mono 8bridged-tied load (BTL) with 1% THD+N and  
115mW (typ) per channel of continuous average power into  
stereo 32BTL loads with 0.5% THD+N, using a 5V power  
supply.  
Features  
n 1.1W (typ) output power with 8mono BTL load  
n 115mW (typ) output power with stereo 32BTL loads  
n SPI programmable 32 step digital volume control  
n Eight distinct output modes  
The LM4855 features a 32 step digital volume control and  
eight distinct output modes. The digital volume control and  
output modes are programmed through a three-wire SPI  
serial control interface, that allows flexibility in routing and  
mixing audio channels.  
n micro-SMD and LLP surface mount packaging  
n "Click and Pop" suppression circuitry  
n Thermal shutdown protection  
The LM4855 is designed for cellular phone, PDA, and other  
portable handheld applications. It delivers high quality output  
power from a surface-mount package and requires only six  
external components.  
n Low shutdown current (0.1uA, typ)  
The industry leading micro SMD package only utilizes 2mm  
x 2.3mm of PCB space, making the LM4855 the most space  
efficient audio sub system available today.  
Applications  
n Moblie Phones  
n PDAs  
Typical Application  
200395D1
