The LM4902 is a bridged audio power amplifier capable of delivering 265mW of continuous average power into an 8Ω 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 LM4902 does not require output coupling capacitors, bootstrap capacitors or snubber networks, it is optimally suited for low-power portable applications.
The LM4902 features an externally controlled, low power consumption shutdown mode, and thermal shutdown protection.
The closed loop response of the unity-gain stable LM4902 can be configured by external gain-setting resistors.
