General Description
The LM4880 is a dual audio power amplifier capable of delivering typically 250mW per channel of continuous
average power to an 8Ohm load with 0.1% THD+N using 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 LM4880 does not require bootstrap capacitors or snubber networks, it is optimally suited for low-
power portable 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.
