LM4858  
Mono 1.5 W / Stereo 300mW Power Amplifier  
General Description  
Key Specifications  
n Output Power at 1% THD+N, 1kHz:  
The LM4858 is an audio power amplifier capable of deliver-  
ing 1.5W (typ) of continuous average power into a mono 4  
bridged-tied load (BTL) with 1% THD+N or 95mW per chan-  
nel of continuous average power into stereo 32single-  
ended (SE) loads with 1% THD+N, using a 5V power supply.

The LM4858 can automatically switch between mono BTL  
and stereo SE modes utilizing a headphone sense pin. It is  
ideal for any system that provides both a monaural speaker  
output and a stereo line or headphone output  
n THD+N at 1kHz, 95mW into 32SE  
n Single Supply Operation  
n Shutdown Current  
2.4 to 5.5V  
18µA (typ)  
Boomer audio power amplifiers were designed specifically to  
provide high quality output power with a minimal amount of  
external components. Since the LM4858 does not require  
bootstrap capacitors or snubber networks, it is optimally  
suited for low-power portable systems.  
Features  
n Mono 1.5W BTL or stereo 300mW output  
n Logic controlled headphone sense  
n “Click and pop” suppression circuitry  
n No bootstrap capacitors required  
n Thermal shutdown protection  
n Unity-gain stable  
The LM4858 features an externally controlled, micropower  
consumption shutdown mode and thermal shutdown protec-  
tion. The unity-gain stable LM4858’s gain is set by external  
gain-setting resistors  
n Available in space-saving MSOP and LLP packaging  
Applications  
n Portable computers  
n Desktop computers  
n PDA’s  
n Handheld games
