LM4908 10kV ESD Rated, Dual 120mW Headphone Amplifier

The LM4908 is a dual audio power amplifier capable of delivering 120mW 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 LM4908 does not require bootstrap capacitors or snubber networks, it is optimally suited for low-power portable systems.

The unity-gain stable LM4908 can be configured by external gain-setting resistors.
