LM4881
Dual 200 mW Headphone Amplifier with Shutdown Mode
General Description
The LM4881 is a dual audio power amplifier capable of deliv-
ering 200 mW of continuous average power into an 8
load
with 0.1% (THD) 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 LM4881 does not require bootstrap capacitors or snub-
ber networks, it is optimally suited for low-power portable
systems.
The LM4881 features an externally controlled, low power
consumption shutdown mode which is virtually clickless and
popless, as well as an internal thermal shutdown protection
mechanism.
The unity-gain stable LM4881 can be configured by external
gain-setting resistors.
