LM4864LD-LM4864M-LM4864MM-LM4864MMX-LM4864MX-LM4864N
300 mW Audio Power Amplifier with Shutdown Mode
LM4864
725mW Audio Power Amplifier with Shutdown Mode
General Description

The LM4864isa bridged audio power amplifier capableof
delivering 725mWof continuous average power intoan8Ω
load with 1% THD+N froma5V power supply.
Boomer® audio power amplifiers were designed specifically provide high quality output power froma low supply volt-
age while requiringa minimal amountof external compo-
nents. Since the LM4864 does not require output coupling
capacitors, bootstrap capacitorsor snubber networks,itis
optimally suitedfor low-power portable applications.
The LM4864 featuresan externally controlled, low power
consumption shutdown mode, and thermal shutdown protec-
tion.
The closed loop responseof the unity-gain stable LM4864
canbe configuredby external gain-setting resistors. The
deviceis availablein multiple package typesto suit various
applications.
