LM4898  
1 Watt Fully Differential Audio Power Amplifier With  
Shutdown Select  
General Description  
Key Specifications  
The LM4898 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 1 watt of continuous average  
power to an 8Ω BTL load with less than 1% distortion  
(THD+N) from a 5VDC power supply.

Improved PSRR at 217Hz  
Power Output at 5.0V & 1% THD  
Power Output at 3.3V & 1% THD

1.0W(typ)  
400mW(typ)

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 appli-  
cations where minimal power consumption is a primary re-  
quirement.  
Features  
n Fully differential amplification  
n Available in space-saving packages micro SMD, MSOP,  
and LLP  
n Ultra low current shutdown mode  
n Can drive capacitive loads up to 500pF  
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 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 Shut-  
down. Additionally, the LM4898 features an internal thermal  
shutdown protection mechanism.  
n Shutdown high or low selectivity  
The LM4898 contains advanced pop & click circuitry which  
virtually eliminates noises which would otherwise occur dur-  
ing turn-on and turn-off transitions.  
Applications  
n Mobile phones  
n PDAs  
n Portable electronic devices
