Mode
Check for Samples: LM4818 FEATURES DESCRIPTION The LM4818 is a mono bridged power amplifier that
is capable of delivering 350mWRMS output power into
a 16Ω load or 300mWRMS output power into an 8Ω
load with 10% THD+N from a 5V power supply. 1 23 SOIC Surface Mount Packaging.
Switch On/Off Click Suppression.
Unity-Gain Stable.
Minimum External Components. APPLICATIONS General Purpose Audio
Portable Electronic Devices
Information Appliances (IA) KEY SPECIFICATIONS THD+N at 1kHz, 350mW Continuous Average
Output Power into 16Ω 10% (max)
THD+N at 1kHz, 300mW Continuous Average
Output Power into 8Ω 10% (max)
Shutdown Current 0.7ВµA (typ) The LM4818 Boomerв„ў audio power amplifier is
designed specifically to provide high quality output
power and minimize PCB area with surface mount
packaging and a minimal amount of external
components. Since the LM4818 does not require
output coupling capacitors, bootstrap capacitors or
snubber networks, it is optimally suited for low-power
portable applications. …
