General Description
The LM4863 is a dual bridge-connected audio power amplifier which, when connected to a 5V supply, will
deliver 2.2W to a 4Ohm load or 2.5W to a 3Ohm load with less than 1.0% THD+N. In addition, the
headphone input pin allows the amplifiers to operate in single-ended mode when driving stereo headphones.
Boomer audio power amplifiers were designed specifically to provide high quality output power from a
surface mount package while requiring few external components. To simplify audio system design, the
LM4863 combines dual bridge speaker amplifiers and stereo headphone amplifiers on one chip.
The LM4863 features an externally controlled, low-power consumption shutdown mode, a stereo headphone
amplifier mode, and thermal shutdown protection. It also utilizes circuitry to reduce "clicks and pops" during
device turn-on.
