General Description
The LM4882 is a single-ended audio power amplifier capable of delivering 250mW of continuous
average power into an 8Ohm load with 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 LM4882 does not
require bootstrap capacitors or snubber networks, it is optimally suited for low-power portable systems.
The LM4882 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 LM4882 can be configured by external gain-setting resistors.
