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.
