Introduction

AI Translation

LM4871 is a single-channel Class AB audio power amplifier capable of delivering 2.6W into a 4Ω load at 5.0V supply voltage with 10% THD+N. Its application circuit is simple, requiring minimal external components to achieve high-quality, low-distortion audio output. The device features a shutdown function for significantly extended system standby time, built-in thermal protection for enhanced system reliability, and integrated pop suppression for improved listening experience and simplified system debugging.
