LM4864 300 mW Audio Power Amplifier with Shutdown Mode September 1999 LM4864 300 mW Audio Power Amplifier with Shutdown Mode General Description The LM4864 is a bridged audio power amplifier capable of delivering 300 mW of continuous average power into an 8Ω load with 1% (THD) 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.
