LM4818

具有关断模式的 350W 单声道、模拟输入 AB 类音频放大器; • SOIC Surface Mount Packaging.\n• Switch On/Off Click Suppression.\n• Unity-Gain Stable.\n• Minimum External Components. \n Key Specifications \n• THD+N at 1kHz, 350mW Continuous Average Output Power into 16Ω 10% (max)\n• THD+N at 1kHz, 300mW Continuous Average Output Power into 8Ω 10% (max)\n• Shutdown Current 0.7µA (typ);

The LM4818 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 LM4818 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 LM4818 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 LM4818 can be configured using external gain-setting resistors. The device is available in SOIC package type to suit various applications.
