LM4808 www.ti.com SNAS051D – FEBRUARY 2000 – REVISED MAY 2013 LM4808 Low Voltage High Power Audio Power Amplifier Check for Samples: LM4808 FEATURES 1 2 WSON, VSSOP, and SOIC Surface Mount Packaging Switch On/Off Click Suppression Excellent Power Supply Ripple Rejection Unity-Gain Stable Minimum External Components APPLICATIONS Headphone Amplifier Personal Computers Portable Electronic Devices DESCRIPTION The LM4808 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 using surface mount packaging. Since the LM4808 does not require bootstrap capacitors or snubber networks, it is optimally suited for low-power portable systems. The unity-gain stable LM4808 can be configured by external gain-setting resistors. KEY SPECIFICATIONS THD+N at 1kHz at 105mW Continuous Average Output Power Into 16Ω 0.1 % (typ) THD+N at 1kHz at 70mW Continuous Average Output Power Into 32Ω 0.1 % (typ) Output Power at 0.1% THD+N at 1kHz Into 32Ω 70 mW (typ) 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
