LM4668  
10W High-Efficiency Mono BTL Audio Power Amplifier  
General Description  
Key Specifications  
The LM4668 is a high efficiency switching audio power  
amplifier primarily designed for demanding applications in  
flat panel monitors and TV’s. It is capable of delivering 6W to  
an 8mono BTL load with less than 1% distortion (THD+N)  
from a 12VDC power supply.

Boomer audio power amplifiers were designed specifically to  
provide high quality output power with a minimal amount of  
external components. The LM4668 features a micro-power,  
active-low shutdown mode, an internal thermal shutdown  
protection mechanism, and short circuit protection.

Fixed Gain  
The LM4668 contains advanced transient (“pop and click”)  
suppression circuitry that eliminates noises that would oth-  
erwise occur during turn-on and turn-off transitions.
