General Description
The LM4873 is a dual bridge-connected audio power amplifier which, when connected to a 5V supply, will
deliver 2.1W to a 4
load or 2.4W to a 3
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. A MUX
control pin allows selection between the two stereo sets of amplifier inputs. The MUX control can also be
used to select two different closed-loop responses.
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
LM4873 combines dual bridge speaker amplifiers and stereo headphone amplifiers on one chip.
The LM4873 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.
