LM4808
Dual 105 mW Headphone Amplifier
General Description
The LM4808 is a dual audio power amplifier capable of deliv-
ering 105 mW per channel of continuous average power into
a 16
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 snub-
ber networks, it is optimally suited for low-power portable
systems.
The unity-gain stable LM4808 can be configured by external
gain-setting resistors.
