MC4863
Dual 2.2W Audio Amplifier Plus Stereo Headphone Function
General Description
The MC4863 is a dual bridge-connected audio
power amplifier which, when connected to a 5V
supply, will deliver 2.2W to a 4Ω load(No t e 1) or
2.5W to a 3Ω load(Note 2) with less than 1.0%
THD+N. In addition, the headphone input pin
allows the amplifiers to operate in single-ended
mode to drive 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, it combines dual bridge speaker amp-
lifiers and stereo headphone amplifiers on one
chip.
The MC4863 features an externally controlled,
low-power consumption shutdown mode, a stereo
headphone amplifier mode, and thermal shut-
down protection. It also utilizes circuitry to reduce
“clicks and pops” during device turn-on.

Note 1: An MC4863 which has been properly mounted to the circuit board will deliver 2.2W into 4Ω.The other
package options for the MC4863 will deliver 1.1W into 8Ω. See the Application Information section for MC4863
usage infor-mation.
Note 2: An MC4863 which has been properly mounted to the circuit board and forced-air cooled will deliver 2.5W
into 3Ω.
