com LM4811 Dual 105mW Headphone Amplifier with Digital Volume Control and Shutdown Mode December 2002 LM4811 Dual 105mW Headphone Amplifier with Digital Volume Control and Shutdown Mode General Description The LM4811 is a dual audio power amplifier capable of delivering 105mW per channel of continuous average power into a 16Ω 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.
