LM4863
Dual 2.2W Audio Amplifier Plus Stereo Headphone
Function
General Description
The LM4863 is a dual bridge-connected audio power ampli-
fier which, when connected to a 5V supply, will deliver 2.2W
toa4
load (Note 1) or 2.5W to a 3 load (Note 2) with less
than 1.0% THD+N. In addition, the headphone input pin al-
lows 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 sim-
plify 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 cir-
cuitry to reduce “clicks and pops” during device turn-on.
Note 1: An LM4863MTE or LM4863LQ that has been properly mounted to
a circuit board will deliver 2.2W into 4
. The other package options for the
LM4863 will deliver 1.1W into 8
. See the Application Information sections
for further information concerning the LM4863MTE and LM4863LQ.
Note 2: An LM4863MTE or LM4863LQ that has been properly mounted to a
circuit board and forced-air cooled will deliver 2.5W into 3
.
