LM4668 - 10W High-Efficiency Mono BTL Audio Power Amplifier

National Semiconductor

Datasheet Details

The LM4668 is a high efficiency switching audio power amplifier primarily designed for demanding applications in flat panel monitors and TV’s..

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.
