Headphone AMP Click Board

The Headphone AMP Click Board™ is a compact add-on board that contains a stereo headphone amplifier. This board features the LM4811, Boomer® audio power amplifier capable of delivering 105mW per channel with digital volume control from Texas Instruments. The Boomer® amplifiers are specifically designed 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. It features a digital volume control that sets the amplifier's gain from +12dB to ?33dB in 16 discrete steps, in addition to a micro-power consumption Shutdown mode. This Headphone AMP Click Board™ is suitable for portable electronics and audio systems, representing a perfect solution for remote, headphone audio-volume control applications.
