The National Semiconductor Boomer® LM4892IBP is an 8-uSMD (1.36x1.36) surface-mount audio amplifier IC. This Class AB amplifier delivers 1W into an 8-ohm load and 90mW into a 32-ohm load from a 2.2V to 5.5V supply. It features a single-channel mono output with dedicated mono headphone drive, making it suitable for portable audio applications. Key integrated features include depop circuitry for silent power-up/down, a shutdown pin for power management, and thermal protection to prevent damage. This component is widely utilized in consumer electronics, mobile devices, and audio systems requiring efficient, low-power amplification. The LM4892IBP is supplied in bulk packaging.
