Product Summary

The LM4902MMX is a bridged audio power amplifier capable of delivering 265mW of continuous average power into an 8W load with 1% THD+N from a 3.3V 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 LM4902MMX does not require output coupling capacitors, bootstrap capacitors or snubber networks, it is optimally suited for low-power portable applications. The LM4902MMX features an externally controlled, low power consumption shutdown mode, and thermal shutdown protection. The closed loop response of the unity-gain stable LM4902MMX can be configured by external gain-setting resistors.
