FEATURES  
DESCRIPTION  
The LM4838 is a monolithic integrated circuit that  
provides DC volume control, and stereo bridged  
audio power amplifiers capable of producing 2W into  
4Ω with less than 1.0% THD or 2.2W into 3Ω with  
less than 1.0% THD (see Notes below).

Stereo Switchable Bridged/Single-Ended  
Power Amplifiers  
•
Selectable Internal/External Gain and Bass  
Boost  
Boomer™ audio integrated circuits were designed  
specifically to provide high quality audio while  
requiring a minimum amount of external components.  
The LM4838 incorporates a DC volume control,  
•
•
“Click and Pop” Suppression Circuitry  
Thermal Shutdown Protection Circuitry  
stereo bridged audio power amplifiers and  
a
selectable gain or bass boost, making it optimally  
suited for multimedia monitors, portable radios,  
desktop, and portable computer applications.  
APPLICATIONS  
•
•
•
Portable and Desktop Computers  
Multimedia Monitors  
The LM4838 features an externally controlled, low-  
power consumption shutdown mode, and both a  
power amplifier and headphone mute for maximum  
system flexibility and performance.  
Portable Radios, PDAs, and Portable TVs  
Note: When properly mounted to the circuit board,  
the LM4838NJB, LM4838PWP, and LM4838NYC will  
deliver 2W into 4Ω. The LM4838PW and LM4838YZR  
will deliver 1.1W into 8Ω. See Application Information  
section Exposed-DAP package PCB Mounting  
Considerations for more information.  
Note: An LM4838NJB and LM4838PWP that have  
been properly mounted to the circuit board and  
forced-air cooled will deliver 2.2W into 3Ω.
