The LM4808 is a dual audio power amplifier capable of delivering 105mW per channel of continuous average power into a 16? 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.
