LM4811 Dual 105mW Headphone Amplifier

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 com.

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 shutdow
