LM4879  
1.1 Watt Audio Power Amplifier  
General Description  
Key Specifications  
The LM4879 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 1.1 watt of continuous average power to an 8  
BTL load with less than 1% distortion (THD+N) from a 5VDC  
power supply.

Boomer audio power amplifiers were designed specifically to  
provide high quality output power with a minimal amount of  
external components. The LM4879 does not require output  
coupling capacitors or bootstrap capacitors, and therefore is  
ideally suited for lower-power portable applications where  
minimal space and power consumption are primary require-  
ments.  
Features  
n No output coupling capacitors, snubber networks or  
bootstrap capacitors required  
n Unity gain stable  
n Ultra low current shutdown mode  
n Fast turn on: 80ms (typ), 110ms (max) with 1.0µF  
capacitor  
n BTL output can drive capacitive loads up to 100pF  
n Advanced pop & click circuitry eliminates noises during  
turn-on and turn-off transitions  
n 2.2V - 5.0V operation  
n Available in space-saving µSMD, LLP, and MSOP  
packages  
The LM4879 features a low-power consumption global shut-  
down mode, which is achieved by driving the shutdown pin  
with logic low. Additionally, the LM4879 features an internal  
thermal shutdown protection mechanism.  
The LM4879 contains advanced pop & click circuitry which  
eliminates noises which would otherwise occur during  
turn-on and turn-off transitions.  
The LM4879 is unity-gain stable and can be configured by  
external gain-setting resistors.  
Applications  
n Mobile Phones  
n PDAs  
n Portable electronic devices
