Mono 1.5 W / Stereo 300mW Power Amplifier
LM4853
Mono 1.5 W/ Stereo 300mW Power Amplifier
General DescriptionThe LM4853isan audio power amplifier capableof deliver-
ing 1.5W (typ)of continuous average power intoa mono4Ω
bridged-tied load (BTL) with 1% THD+Nor 95mWper chan-
nelof continuous average power into stereo 32Ω single-
ended (SE) loads with 1% THD+N, usinga5V power supply.
The LM4853 can automatically switch between mono BTL
and stereoSE modes utilizinga headphone sense pin.Itis
idealfor any system that provides botha monaural speaker
output anda stereo lineor headphone output
Boomer audio power amplifiers were designed specificallyto
provide high quality output power witha minimal amountof
external components. Since the LM4853 does not require
bootstrap capacitorsor snubber networks,itis optimally
suitedfor low-power portable systems.
The LM4853 featuresan externally controlled, micropower
consumption shutdown mode and thermal shutdown protec-
tion. The unity-gain stable LM4853’s gainissetby external
gain-setting resistors
