Product Summary

The LM4819M is a mono bridged power amplifier that is capable of delivering 350mWRMS output power into a 16W load or 300mWRMS output power into an 8W load with 10% THD+N from a 5V power supply. The LM4819M Boomer audio power amplifier is designed specifically to provide high quality output power and minimize PCB area with surface mount packaging and a minimal amount of external components. Since the LM4819M does not require output coupling capacitors, bootstrap capacitors or snubber networks, it is optimally suited for low-power portable applications. The closed loop response of the unity-gain stable can be configured using external gain-setting resistors. The LM4819M is available in SO package types to suit applications including General purpose audio, Portable electronic devices and Information Appliances (IA).
