LM4859
Stereo 1.2W Audio Sub-system with 3D Enhancement
General Description
The LM4859 is an integrated audio sub-system designed for
stereo cell phone applications. Operating on a 3.3V supply, it
combines a stereo speaker amplifier delivering 495mW per
channel into an 8
load and a stereo headphone amplifier
delivering 33mW per channel into a 32
load. It integrates
the audio amplifiers, volume control, mixer, power manage-
ment control, and National 3D enhancement all into a single
package. In addition, the LM4859 routes and mixes the
stereo and mono inputs into 10 distinct output modes. The
LM4859 is controlled through an I
2
C compatible interface.
Other features include an ultra-low current shutdown mode
and thermal shutdown protection.
Boomer audio power amplifiers are designed specifically to
provide high quality output power with a minimal amount of
external components.
The LM4859 is available in a 28–lead LLP package.
