Stereo 2W Audio Power Amplifiers with DC Volume Control, Bass Boost, and Input Mux
LM4836
Stereo 2W Audio Power Amplifiers
with DC Volume Control, Bass Boost, and Input Mux
General DescriptionThe LM4836isa monolithic integrated circuit that provides volume control, and stereo bridged audio power amplifi-
ers capableof producing 2W into4Ω (Note1) with less than
1.0% THD+N,or 2.2W into3Ω (Note2) with less than 1.0%
THD+N.
Boomer® audio integrated circuits were designed specifically provide high quality audio while requiringa minimum
amountof external components. The LM4836 incorporatesa volume control, stereo bridged audio power amplifiers,
selectable gainor bass boost, andan input mux makingit
optimally suitedfor multimedia monitors, portable radios,
desktop, and portable computer applications.
The LM4836 featuresan externally controlled, low-power
consumption shutdown mode, and botha power amplifier
and headphone mutefor maximum system flexibility and
performance.
Note1: When properly mountedtothe circuit board,the LM4836LQand
LM4836MTEwill deliver2Winto4Ω.The LM4836MTwill deliver 1.1Winto
8Ω.Seethe Application Informationsectionfor LM4836LQand LM4836MTE
usage information.
Note2:An LM4836LQand LM4836MTEthat have been properly mountedthe circuit boardand forced-air cooledwill deliver 2.2Winto3Ω.
