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.
