LM4819 is a 350mW Audio Power Amplifier with Shutdown Mode

This post sponsored by Texas Instruments.

The LM4819 is a mono bridged power amplifier that is capable of delivering 350mWRMS output power into a 16Ω load or 300mWRMS output power into an 8Ω load with 10% THD+N from a 5V power supply. 

The LM4819 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 LM4819 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 LM4819 can be configured using external gain-setting resistors. The device is available in WSON, VSSOP, and SOIC package types to suit various applications. Applications include general purpose audio, portable electronic devices, and information appliances (IA). The LM4819 has switch on/off click suppression.
