LM4880
Dual 250 mW Audio Power Amplifier with Shutdown
Mode
General Description
The LM4880 is a dual audio power amplifier capable of deliv-
ering typically 250 mW per channel of continuous average
power to an 8
load with 0.1% (THD) using a 5V power sup-
ply.
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 LM4880 does not require bootstrap capacitors or
snubber networks, it is optimally suited for low-power por-
table systems.
The LM4880 features an externally controlled, low-power
consumption shutdown mode, as well as an internal thermal
shutdown protection mechanism.
The unity-gain stable LM4880 can be configured by external
gain-setting resistors.
