1 Watt Audio Power Amplifier in micro SMD package
LM4872 Watt Audio Power Amplifier in micro SMD package
General DescriptionThe LM4872isa bridge-connected audio power amplifier
capableof delivering1Wof continuous average powertoan load with less than .2% (THD) froma5V power supply.
Boomer audio power amplifiers were designed specificallyto
provide high quality output power witha minimal amountof
external components. Since the LM4872 does not require
output coupling capacitorsor bootstrap capacitors.Itis op-
timally suitedfor low-power portable applications.
The LM4872 featuresan externally controlled, low-power
consumption shutdown mode,as wellasan internal thermal
shutdown protection mechanism.
The unity-gain stable LM4872 canbe configuredby external
gain-setting resistors.
Key Specifications Power Outputat 0.2% THD 1W (typ) Shutdown Current 0.01µA (typ)
Features micro SMD package (see App. note AN-1112)5V-2V operation No output coupling capacitorsor bootstrap capacitors. Unity-gain stable External gain configuration capability
