350mW Audio Power Amplifier with Shutdown Mode
General Description
The LM4818isa mono bridged power amplifier thatis ca-
pableof delivering 350mWRMS output power intoa 16Ω load 300mWRMS output power intoan 8Ω load with 10%
THD+N froma5V power supply.
The LM4818 Boomer audio power amplifieris designed
specificallyto provide high quality output power and mini-
mize PCB area with surface mount packaging anda minimal
amountof external components. Sincethe LM4818 doesnot
require output coupling capacitors, bootstrap capacitorsor
snubber networks,itis optimally suitedfor low-power por-
table applications.
The closed loop responseof the unity-gain stable LM4818
canbe configured using external gain-setting resistors. The
deviceis availablein SO package typeto suit various appli-
cations.
Key Specifications THD+Nat 1kHz, 350mW continuous average output
power into 16Ω 10% (max) THD+Nat 1kHz, 300mW continuous average output
power into8Ω 10% (max) Shutdown Current 0.7µA (typ)
Features SOP surface mount packaging. Switch on/off click suppression. Unity-gain stable. Minimum external components.
