LM3886 High-Performance 68W Audio Power Amplifier w/Mute

LM3886 High-Performance 68W Audio Power Amplifier IC with SPiKe Protection & Mute

The LM3886 is a high-performance audio power amplifier integrated circuit. It's engineered for demanding audio applications, delivering an impressive 68W of continuous average power into a 4Ω load. This amplifier maintains exceptional sound quality with an ultra-low THD+N of 0.03% across the audio spectrum. Advanced Self Peak Instantaneous Temperature (°Ke) (SPiKe) protection circuitry ensures unparalleled reliability. This robust system safeguards against overvoltage, undervoltage, overloads, and thermal runaway. With a signal-to-noise ratio greater than 92dB, it provides a clean and powerful audio signal. An integrated input mute function adds convenience for system control. The LM3886 is a superior choice for high-fidelity audio systems and professional sound equipment.
