Stereo 2W Audio Power Amplifiers with DC Volume Control and Selectable Gain
LM4835
Stereo 2W Audio Power Amplifiers
with DC Volume Control and Selectable Gain
General DescriptionThe LM4835isa monolithic integrated circuit that provides volume control, and stereo bridged audio power amplifi-
ers capableof producing 2W into4Ω (Note1) with less than
1.0% THDor 2.2W into 3Ω (Note2) with less than 1.0%
THD.
Boomer® audio integrated circuits were designed specifically provide high quality audio while requiringa minimum
amountof external components. The LM4835 incorporatesa volume control, stereo bridged audio power amplifiers
anda selectable gainor bass boost, makingit optimally
suitedfor multimedia monitors, portable radios, desktop, and
portable computer applications.
The LM4835 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 LM4835LQand
LM4835MTEwill deliver2Winto4Ω.The LM4835MTwill deliver 1.1Winto
8Ω.Seethe Application Informationsection LM4835LQ andfor LM4835MTE
usage information.
Note2:An LM4835LQand LM4835MTEthat have been properly mountedthe circuit boardand forced-air cooledwill deliver 2.2Winto3Ω.
