Audio Amp Headphone 2-CH Stereo 0.3W Class-AB 8-Pin MSOP T/R, LM4881MM/NOPB, Texas Instruments

The LM4881 is a dual audio power amplifier capable of delivering 200mW of continuous average power into an 8? 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 LM4881 does not require bootstrap capacitors or snubber 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.
