LM4927  
2.5 Watt Fully Differential Audio Power Amplifier With  
Shutdown  
General Description  
Key Specifications  
The LM4927 is a fully differential audio power amplifier  
primarily designed for demanding applications in mobile  
phones and other portable communication device applica-  
tions. It is capable of delivering 2.5 watts of continuous  
average power to a 4load with less than 10% distortion  
(THD+N) from a 5VDC power supply.

Shutdown Current  
Boomer audio power amplifiers were designed specifically to  
provide high quality output power with a minimal amount of  
external components. The LM4927 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.  
Features  
n Fully differential amplification  
n Available in space-saving micro-array LLP package  
n Ultra low current shutdown mode  
n Can drive capacitive loads up to 100pF  
n Improved pop & click circuitry eliminates noises during  
turn-on and turn-off transitions  
n 2.4 - 5.5V operation  
n No output coupling capacitors, snubber networks or  
bootstrap capacitors required  
The LM4927 features a low-power consumption shutdown  
mode. To facilitate this, Shutdown may be enabled by logic  
low. Additionally, the LM4927 features an internal thermal  
shutdown protection mechanism.  
The LM4927 contains advanced pop & click circuitry which  
eliminates noises which would otherwise occur during  
turn-on and turn-off transitions.  
Applications  
n Mobile phones  
n PDAs  
n Portable electronic devices
