General Description

The LM4864 is a bridged audio power amplifier capable of delivering 725mW of continuous average power into an 8 load with 1% THD+N from a 5V power supply.

Boomer® audio power amplifiers were 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.

Features

MSOP, SOP, DIP, and LD packaging
No output coupling capacitors, bootstrap capacitors, or snubber circuits are necessary
Thermal shutdown protection circuitry
Unity-gain stable
External gain configuration capability
