The LM4894 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.  
Features  
n Fully differential amplification  
Boomer audio power amplifiers were designed specifically to  
provide high quality output power with a minimal amount of  
external components. The LM4894 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.  
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 2.2 - 5.5V operation  
n No output coupling capacitors, snubber networks or  
bootstrap capacitors required  
The LM4894 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 LM4894 features an internal thermal  
shutdown protection mechanism.  
n Unity-gain stable  
n External gain configuration capability  
n Shutdown high or low selectivity  
n High CMRR  
The LM4894 contains advanced pop & click circuitry which  
eliminates noises which would otherwise occur during  
turn-on and turn-off transitions.  
Applications  
n Mobile phones  
The LM4894 is unity-gain stable and can be configured by  
external gain-setting resistors.  
n PDAs  
n Portable electronic devices
