LM4668LD 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 mono 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.

    The LM4668 contains advanced transient ("pop and click") suppression circuitry that eliminates noises that would otherwise occur during turn-on and turn-off transitions.
