DESCRIPTION
The LM4808 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.
Boomer audio power amplifiers were designed
specifically to provide high quality output power with a
minimal amount of external components using
surface mount packaging. Since the LM4808 does
not require bootstrap capacitors or snubber networks,
it is optimally suited for low-power portable systems.
The unity-gain stable LM4808 can be configured by
external gain-setting resistors.
