Additional preview pages of the LM4668 datasheet.

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 8Ω mono BTL load with less than 1% distortion (THD+N) from a 12VDC power supply.

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.
