LM4841 Boomer® Audio Power Amplifier Series Stereo 2W Amplifiers with DC Volume  
Control, Transient Free Outputs, and Cap-less Headphone Drive  
Check for Samples: LM4841

FEATURES  
DESCRIPTION  
The LM4841 is a monolithic integrated circuit that  
provides DC volume control and stereo bridged audio  
power amplifiers capable of producing 2W into 4Ω or  
23  
•
Stereo Headphone Amplifier Mode that  
Eliminates the Output Coupling Capacitors  
(Patent Pending)  
(1)  
2.2W into 3Ω with less than 1.0% THD (see (2)).  
•
Acoustically Enhanced DC Volume Control  
Taper  
The LM4841 uses advanced, latest generation  
circuitry to eliminate all traces of clicks and pops  
when the supply voltages is first applied. The  
amplifier has a headphone-amplifier-select input pin  
that is used to switch the amplifiers from bridge to  
single-ended mode for driving headphones. A new  
circuit topology eliminates headphone output coupling  
capacitors (patent pending).  
Boomer® audio integrated circuits are designed  
specifically to provide high quality audio while  
requiring a minimum amount of external components.  
The LM4841 incorporates a DC volume control,

Power Amplifiers  
•
•
•
Selectable Internal/External Gain and Bass  
Boost  
Advanced “Click and Pop” Suppression  
Circuitry  
Thermal Shutdown Protection Circuitry  
APPLICATIONS  
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.  
•
•
•
Portable and Desktop Computers  
Multimedia Monitors  
Portable Radios, PDAs, and Portable TVs  
The LM4841 features an externally controlled, low-  
power consumption shutdown mode (Shutdown Low),  
and both a power amplifier and headphone mute for  
maximum system flexibility and performance.

Into 3Ω (MH and LQ): 2.2W (typ)  
Into 4Ω (MH and LQ): 2.0W (typ)  
Into 8Ω (MT, MH, and LQ): 1.1W (typ)  
(1) When properly mounted to the circuit board, LM4841MH and  
LM4841LQ will deliver 2W into 4Ω. The LM4841MT will  
deliver 1.1W into 8Ω. See the APPLICATION INFORMATION  
section for LM4841MH usage information.  
(2) An LM4841MH that has been properly mounted to the circuit  
board and forced-air cooled will deliver 2.2W into 3Ω.
