FEATURES  
DESCRIPTION  
The LM4898 is a fully differential audio power  
amplifier primarily designed for demanding  
applications in mobile phones and other portable  
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.

Ultra Low Current Shutdown Mode  
Can Drive Capacitive Loads up to 500pF  
Improved Pop and Click Circuitry Eliminates  
Noises During Turn-On and Turn-Off  
Transitions  
Boomer audio power amplifiers were designed  
specifically to provide high quality output power with a  
minimal amount of external components. The  
LM4898 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.

•
2.4 - 5.5V Operation  
No Output Coupling Capacitors, Snubber  
Networks or Bootstrap Capacitors Required  
•
Shutdown High or Low Selectivity  
APPLICATIONS  
The LM4898 features a low-power consumption  
shutdown mode. To facilitate this, Shutdown may be  
enabled by either logic high or low depending on  
mode selection. Driving the shutdown mode pin either  
high or low enables the shutdown select pin to be  
driven in a likewise manner to enable Shutdown.  
Additionally, the LM4898 features an internal thermal  
shutdown protection mechanism.

Shutdown Current: 0.1µA(typ)  
The LM4898 contains advanced pop and click  
circuitry which virtually eliminates noises which would  
otherwise occur during turn-on and turn-off  
transitions.
