The LM4811 is a dual audio power amplifier capable of delivering 105mW per channel of continuous average power into a 16? load with 0.1% (THD+N) from a 5V power supply.
Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components. Since the LM4811 does not require bootstrap capacitors or snubber networks, it is optimally suited for low-power portable systems.
The LM4811 features a digital volume control that sets the amplifier's gain from +12dB to −33dB in 16 discrete steps using a two−wire interface.
The unity-gain stable LM4811 also features an externally controlled, active-high, micropower consumption shutdown mode. It also has an internal thermal shutdown protection mechanism.
