The LM3886TF is an Overture high performance class AB audio power amplifier with mute function in 11 pin TO-220 package. The LM3886 utilizes self peak instantaneous temperature (°Ke) (SPiKe) protection circuitry. This leads to high performance above discrete and hybrid amplifiers by providing an inherently and dynamically protected safe operating area (SOA). SPiKe protection provides output protection against overvoltage, undervoltage, overloads, including shorts to supplies, thermal runaway and instantaneous temperature peaks. The LM3886 maintains an excellent signal to noise ratio of greater than 92dB with a typical low noise floor of 2µV. It provides excellent linearity with an IMD (SMPTE) typical rating of 0.004%.
