1 / 14 page  LM4668 10W High-Efficiency Mono BTL Audio Power Amplifier General Description 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 8 Ω mono BTL load with less than 1% distortion (THD+N) from a 12V DC 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. 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.
