Product Summary

The lm4809mmx is a dual audio power amplifier capable of delivering 105 mW per channel of continuous average power into a 16W 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 lm4809mmx does not require bootstrap capacitors or snubber networks, it is optimally suited for low-power portable systems. The unity-gain stable lm4809mmx can be configured by external gain-setting resistors.
