Product Summary

The LM4809MM/NOPB 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 LM4809MM/NOPB does not require bootstrap capacitors or snubber networks, it is optimally suited for low-power portable systems. The unity-gain stable LM4809MM/NOPB can be configured by external gain-setting resistors.
