The LPA4809 is a dual audio power amplifier capable of delivering 140mW per channel of continuous average power into a 16Ω load with 0.1 %(THD+N) from a 5V power supply. Boomer audio power amplifier was designed specifically to provide high quality output power with a minimal amount of external components. Since the LPA4809 does not require bootstrap capacitors or snubber networks, it is optimally suited for low-power portable systems. The unity-gain stable LPA4809 can be configured by external gain-setting resistors.The LPA4809 features an externally controlled, active-low, micro power consumption shutdown mode, as well as an internal thermal shutdown protection mechanism.
