LM4680
10W High-Efficiency Mono BTL Audio Power Amplifier
General Description
The LM4680 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 10W
to an 8
mono BTL load with less than 10% distortion
(THD+N) when powered from a 14V
DC power supply.
Boomer audio power amplifiers were designed specifically to
provide high quality output power with a minimal amount of
external components. The LM4680 features a micro-power,
active-low shutdown mode, an internal thermal shutdown
protection mechanism, output fault detect, and short circuit
protection.
The LM4680 contains advanced transient (“pop and click”)
suppression circuitry that eliminates noises that would oth-
erwise occur during turn-on and turn-off transitions.
