LM4849
Stereo 2W Audio Power Amplifiers
with DC Volume Control and Input Mux
General Description
The LM4849 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 LM4849 incorporates a
DC volume control, stereo bridged audio power amplifiers,
and an input mux making it optimally suited for multimedia
monitors, portable radios, desktop, and portable computer
applications.
The LM4849 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 LM4849MH will
deliver 2W into 4
. See the Application Information section for LM4849MH
usage information.
Note 2:
An LM4849MH that has been properly mounted to the circuit board
and forced-air cooled will deliver 2.2W into 3
.
