DESCRIPTION
The LM4809 is a dual audio power amplifier capable
of delivering 105mW per channel of continuous
average power into a 16load with 0.1% (THD+N)
from a 5V power supply.
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, active-
low, micropower consumption shutdown mode, as
well as an internal thermal shutdown protection
mechanism.
