FEATURES  
DESCRIPTION  
The LM4867 is a dual bridge-connected audio power  
2
Advanced “Click and Pop” Suppression  
Circuitry  
amplifier which, when connected to a 5V supply, will  
(1)  
(2)  
deliver 2.1W to a 4Ω load  
or 2.4W to a 3Ω load  
Eliminates Headphone Amplifier Output  
Coupling Capacitors (Patent Pending)  
with less than 1.0% THD+N (see notes below). The  
LM4867 uses advanced, latest generation circuitry to  
eliminate all traces of clicks and pops when the  
supply voltage is first applied. The amplifier has a  
headphone-amplifier-select input pin. It 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). A MUX control pin allows selection  
between the two sets of stereo input signals. The  
MUX control can also be used to select between two  
different customer-specified closed-loop responses.

APPLICATIONS  
Multimedia Monitors  
Boomer audio power amplifiers are designed  
specifically to provide high quality output power from  
a surface mount package and require few external  
components. To simplify audio system design, the  
LM4867 combines dual bridge speaker amplifiers and  
stereo headphone amplifiers in one package.  
Portable and Desktop Computers  
Portable Audio Systems  
KEY SPECIFICATIONS  
PO at 1% THD+N  
The LM4867 features an externally controlled power-  
LM4867LQ, 3Load, 2.4W (Typ)  
LM4867LQ, 4Load, 2.1W (Typ)  
LM4867MTE, 4, 1.9W (Typ)  
LM4867MT, 8, 1.1W (Typ)  
saving micropower shutdown mode,  
a
stereo  
headphone amplifier mode, and thermal shutdown  
protection.  
(1) An LM4867LQ or LM4867MTE that has been properly  
mounted to a circuit board will deliver 2.1W into 4. The Mux  
control can also be used to select two different closed-loop  
responses. LM4867MT will deliver 1.1W into 8. See the  
Application Information sections for further information  
concerning the LM4867LQ and the LM4867MT.  
(2) An LM4867LQ or LM4867MTE that has been properly  
mounted to a circuit board and forced-air cooled will deliver  
2.4W into 3.  
Single-Ended Mode - THD+N at 75mW into  
32Ω, 0.5% (Max)  
Shutdown Current, 0.7µA (Typ)
