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

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

The LM3886 is an audio power amplifier integrated circuit. It provides 68W of continuous average power into a 4Ω load. The device maintains a THD+N of 0.03%. SPiKe protection circuitry is integrated, safeguarding against overvoltage, undervoltage, overloads, and thermal runaway. A signal-to-noise ratio greater than 92dB is achieved. An input mute function is included. The LM3886 is suitable for high-fidelity audio systems. Its 11-lead TO-220 package facilitates integration. It operates within a supply voltage range of 20V to 94V.
