LM4953  
Ground-Referenced, Ultra Low Noise, Ceramic Speaker  
Driver  
General Description  
Key Specifications  
The LM4953 is an audio power amplifier designed for driving  
Ceramic Speaker in portable applications. When powered by  
a 3.6V supply, it is capable of forcing 12.6Vpp across a 2µF  
+ 30bridge-tied-load (BTL) with less than 1% THD+N.  
Boomer audio power amplifiers were designed specifically to  
provide high quality output power with a minimal amount of  
external components. The LM4953 does not require boot-  
strap capacitors, or snubber circuits. Therefore it is ideally  
suited for display applications requiring high power and mini-  
mal size.

Features  
n Pop & click circuitry eliminates noise during turn-on and  
turn-off transitions  
The LM4953 features a low-power consumption shutdown  
mode. Additionally, the LM4953 features an internal thermal  
shutdown protection mechanism.

n Thermal shutdown  
The LM4953 contains advanced pop & click circuitry that  
eliminates noises which would otherwise occur during  
turn-on and turn-off transitions.  
n Unity-gain stable  
The LM4953 is unity-gain stable and can be configured by  
external gain-setting resistors.  
n External gain configuration capability
