Part Details:

LM481 April 2006 1Dual LM4811Dual 105mW Headphone Amplifier with Digital Volume 105mW Control and Shutdown ModeGeneral Description Key Specifications The LM4811 is a dual audio power amplifier capable of j THD+N at 1kHz, 105mW continuous Headphone delivering 105mW per channel of continuous average power average output power into 16 0.1% (typ) into a 16 load with 0.1% (THD+N) from a 5V power supply. j THD+N at 1kHz, 70mW continuous Boomer audio power amplifiers were designed specifically toprovide high quality output power with a minimal amount of average power into 32 0.1% (typ) external components. Since the LM4811 does not require j Shutdown Current 0.3µA (typ) bootstrap capacitors or snubber networks, it is optimallysuited for low-power portable systems. Features The LM4811 features a digital volume control that sets the Amplifier amplifier s gain from +12dB to -33dB in 16 discrete steps n Digital volume control range from +12dB to -33dB using a two-wire interface. n LD and MSOP surface mount packaging The unity-gain stable LM4811 also features an externally n "Click and Pop" suppression circuitry controlled, active-high, micropower consumption shutdown n No bootstrap capacitors required mode. It also has an internal thermal shutdown protection n Low shutdown current mechanism. Applications with n Cellular Phones n MP3, CD, DVD players Digital n PDA s n Portable electronics Connection Diagrams LD Package Volume MSOP Package Control 20006102 Top View Order Number LM4811MM and See NS Package Number MUB10A Shutdown 20006162
