Texas Instruments  LM4819MX/NOPB

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.
