Check for Samples: LM4809, LM4809LQBD FEATURES DESCRIPTION The LM4809 is a dual audio power amplifier capable
of delivering 105mW per channel of continuous
average power into a 16Ω load with 0.1% (THD+N)
from a 5V power supply. 1 2 Active-Low Shutdown Mode
"Click and Pop" Reduction Circuitry
Low Shutdown Current
WSON, MSOP, and SOIC Surface Mount
Packaging
No Bootstrap Capacitors Required
Unity-Gain Stable APPLICATIONS Headphone Amplifier
Personal Computers
Microphone Preamplifier
PDA's Boomer audio power amplifiers were designed
specifically to provide high quality output power with a
minimal amount of external components. Since the
LM4809 does not require bootstrap capacitors or
snubber networks, it is optimally suited for low-power
portable systems.
The unity-gain stable LM4809 can be configured by
external gain-setting resistors.
The LM4809 features an externally controlled, activelow, micropower consumption shutdown mode, as …
