LM4864M.

The LM4864M is a bridged Audio Power Amplifier capable of delivering 725mW of continuous average power into an 8R load with 1% THD+N from a 5V power supply. Boomer audio power amplifier was designed specifically to provide high quality output power from a low supply voltage while requiring a minimal amount of external components. Since the LM4864 does not require output coupling capacitors, bootstrap capacitors or snubber networks, it is optimally suited for low-power portable applications. The LM4864 features an externally controlled, low power consumption shutdown mode and thermal shutdown protection. The closed loop response of the unity-gain stable LM4864 can be configured by external gain-setting resistors. The device is available in multiple package types to suit various applications.
