LM3876T

TEXAS INSTRUMENTS  LM3876T  音频功率放大器, B, 1通道, 56 W, 24V 至 84V, TO-220, 11 引脚

The is a high-performance Audio Power Amplifier capable of delivering 56W of continuous average power to an 8R load with 0.1% THD+N from 20Hz to 20kHz. The performance of the LM3876, utilizing its Self Peak Instantaneous Temperature °Ke SPiKe protection circuitry, puts it in a class above discrete and hybrid amplifiers by providing an inherently, dynamically protected safe operating area SOA. SPiKe protection means that these parts are completely safeguarded at the output against overvoltage, undervoltage, overloads, including shorts to the supplies, thermal runaway and instantaneous temperature peaks. The LM3876 maintains an excellent signal-to-noise ratio of greater than 95dB minimum with a typical low noise floor of 2.0µV. It exhibits extremely low THD+N values of 0.06% at the rated output into the rated load over the audio spectrum and provides excellent linearity with an IMD SMPTE typical rating of 0.004%.
