LM4836
Stereo 2W Audio Power Amplifiers
with DC Volume Control, Bass Boost, and Input Mux
General Description
The LM4836 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 LM4836 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 LM4836 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 LM4836MTE will
deliver 2W into 4
. The LM4836MT will deliver 1.1W into 8
. See the Appli-
cation Information section for LM4836MTE usage information.
Note 2:
An LM4836MTE which has been properly mounted to the circuit
board and forced-air cooled will deliver 2.2W into 3
.
