LM4809 Datasheet PDF - National

General Description

●The LM4809 is a dual audio power amplifier capable of delivering 105mW per channel of continuous average power into a 16Ωload 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.
