National Semiconductor LM4854LD-NOPB is a Class AB audio amplifier from the Boomer® series. This 1-channel mono amplifier with stereo headphone output is housed in a 14-WSON (4x4) package. It features integrated depop, shutdown, and standby functionalities, along with thermal protection. The device delivers a maximum output power of 2.3W into a 3.2 Ohm load for mono operation, and 200mW into a 16 Ohm load for stereo headphone output. Operating from a 2.4V to 5.5V supply, the LM4854LD-NOPB is suitable for portable audio applications, including mobile phones, personal media players, and other consumer electronics where efficient audio amplification is required. Its surface mount design and compact WSON package facilitate integration into space-constrained printed circuit boards.
