National Semiconductor Boomer® LM4850MM-NOPB is a Class AB audio amplifier IC. This 1-channel (mono) amplifier with stereo headphone output is designed for efficient audio amplification in portable and consumer electronic devices. It delivers up to 1.9W into a 3 Ohm load, and 300mW into an 8 Ohm load for stereo headphone applications. Key features include a low-power shutdown mode, thermal protection, and a depop function to minimize audible noise during power transitions. The device operates from a 2.4V to 5.5V supply voltage and is housed in a 10-VSSOP package, suitable for surface mounting. This component finds application in mobile phones, portable media players, and other battery-powered audio systems.
