FEATURES  
DESCRIPTION  
The LM4928 is an stereo fully differential stereo audio  
power amplifier primarily designed for demanding  
applications in mobile phones and other portable  
communication devices. It is capable of delivering 1.2  
watts of continuous average power to a 8Ω load with  
less than 1% distortion (THD+N) from a 5VDC power  
supply.

•
Ultra Low Current Shutdown Mode  
Can Drive Capacitive Loads up to 100pF  
Boomer audio power amplifiers were designed  
specifically to provide high quality output power with a  
minimal amount of external components. The  
LM4928 does not require output coupling capacitors  
or bootstrap capacitors, and therefore is ideally suited  
for mobile phone and other low voltage applications  
where minimal power consumption is a primary  
requirement.  
Improved Pop & Click Circuitry Eliminates  
Noises During Turn-On and Turn-Off  
Transitions  
•
•
2.4 - 5.5V Operation  
No Output Coupling Capacitors, Snubber  
Networks or Bootstrap Capacitors Required  
APPLICATIONS  
The LM4928 features a low-power consumption  
shutdown mode. To facilitate this, shutdown may be  
enabled by logic low. Additionally, the LM4928  
features an internal thermal shutdown protection  
mechanism.

Mobile Phones  
PDAs  
Portable Electronic Devices and Accessories  
The LM4928 contains advanced pop & click circuitry  
which eliminates noises which would otherwise occur  
during turn-on and turn-off transitions.
