Introduction

AI Translation

The LM4861 is a bridged audio power amplifier capable of delivering 1.1W of continuous average power into an 8Ω load from a 5V supply at 1% THD+N. The Boomer audio power amplifier is designed for use in surface mount packages, delivering high-quality output power with minimal external components. Since the LM4861 requires no output coupling capacitors, bootstrap capacitors, or snubber networks, it is ideal for low-power portable systems. The LM4861 features an externally controlled low-power shutdown mode and an internal thermal shutdown protection mechanism. Unity-gain stable, the LM4861 can be configured with external gain-setting resistors to achieve a differential gain of up to 10 without external compensation components. Higher gains can be achieved with appropriate compensation.
