LM4839
Stereo 2W Audio Power Amplifiers
with DC Volume Control, Bass Boost, and Input Mux
General Description
The LM4839 is a monolithic integrated circuit that provides
DC volume control, and stereo bridged audio power amplifi-
ers capable of producing 2W into 4
(Note 1) with less than
1.0% THD+N, or 2.2W into 3
(Note 2) with less than 1.0%
THD+N.
Boomer audio integrated circuits were designed specifically
to provide high quality audio while requiring a minimum
amount of external components. The LM4839 incorporates a
DC volume control, stereo bridged audio power amplifiers,
selectable gain or bass boost, and an input mux making it
optimally suited for multimedia monitors, portable radios,
desktop, and portable computer applications.
The LM4839 features an externally controlled, low-power
consumption shutdown mode, and both a power amplifier
and headphone mute for maximum system flexibility and
performance.
Note 1: When properly mounted to the circuit board, the LM4839LQ and
LM4839MTE will deliver 2W into 4
. The LM4839MT will deliver 1.1W into
8
. See the Application Information section for LM4839LQ and LM4839MTE
usage information.
Note 2: An LM4839LQ and LM4839MTE that have been properly mounted
to the circuit board and forced-air cooled will deliver 2.2W into 3
.
