LM4892  
1 Watt Audio Power Amplifier with Headphone Sense  
General Description  
Key Specifications  
The LM4892 is an audio power amplifier primarily designed  
for demanding applications in mobile phones and other por-  
table communication device applications. It is capable of  
delivering 1 watt of continuous average power to an 8Ω BTL  
load with less than 1% distortion (THD+N) from a 5VDC  
power supply. Switching between bridged speaker mode and  
headphone (single-ended) mode is accomplished using the  
headphone sense pin.

Features  
Boomer audio power amplifiers are designed specifically to  
provide high quality output power with a minimal amount of  
external components. The LM4892 does not require output  
coupling capacitors or bootstrap capacitors, and therefore is  
ideally suited for mobile phone and other low voltage appli-  
cations where minimal power consumption is a primary re-  
quirement.  
n Available in space-saving packages: LLP, micro SMD,  
MSOP, and SOIC  
n Ultra low current shutdown mode  
n BTL output can drive capacitive loads up to 500pF  
n Improved pop & click circuitry eliminates noise during  
turn-on and turn-off transitions  
n 2.2 - 5.5V operation  
n No output coupling capacitors, snubber networks or  
bootstrap capacitors required  
n Thermal shutdown protection  
n Unity-gain stable  
n External gain configuration capability  
n Headphone amplifier mode  
The LM4892 features a low-power consumption shutdown  
mode, which is achieved by driving the shutdown pin with  
logic low. Additionally, the LM4892 features an internal ther-  
mal shutdown protection mechanism.  
The LM4892 contains advanced pop & click circuitry which  
eliminates noise which would otherwise occur during turn-on  
and turn-off transitions.  
The LM4892 is unity-gain stable and can be configured by  
external gain-setting resistors.  
Applications  
n Mobile Phones  
n PDAs  
n Portable electronic devices
