LM4808 August 2001 Dual LM4808Dual 105 mW Headphone Amplifier 105 General Description Key Specifications The LM4808 is a dual audio power amplifier capable of n THD+N at 1kHz at 105mW continuous average output mW delivering 105mW per channel of continuous average power power into 16 0.1% (typ) into a 16 load with 0.1% (THD+N) from a 5V power supply. n THD+N at 1kHz at 70mW continuous average output Boomer audio power amplifiers were designed specifically to power into 32 0.1% (typ) Headphone provide high quality output power with a minimal amount of n Output power at 0.1% THD+N at 1kHz into 32 70mW external components using surface mount packaging. Since (typ) the LM4808 does not require bootstrap capacitors or snub-ber networks, it is optimally suited for low-power portable Features systems. n LLP, MSOP, and SOP surface mount packaging The unity-gain stable LM4808 can be configured by external n Switch on/off click suppression gain-setting resistors. n Excellent power supply ripple rejection Amplifier n Unity-gain stable n Minimum external components Applicationsn Headphone Amplifier n Personal Computers n Portable electronic devices Typical Application 10127601 *Refer to the Application Information Section for information concerning proper selection of the input and output coupling capacitors.
