LM4766T

TEXAS INSTRUMENTS  LM4766T  音频功率放大器, 2通道, 40 W, 20V 至 60V, TO-220, 15 引脚

The is a dual 40W Audio Amplifier with mute capable of delivering typically 40W per channel with continuous average output power into an 8R load with less than 0.1% THD+N. The performance of the LM4766, utilizing its Self Peak instantaneous temperature °Ke SPiKe protection circuitry, places it in a class above discrete and hybrid amplifiers by providing an inherently, dynamically protected Safe Operating Area SOA. SPiKe protection means that the parts are safeguarded at the output against overvoltage, under-voltage, overloads, including thermal runaway and instantaneous temperature peaks. This amplifier within has an independent smooth transition fade-in/out mute that minimizes output pops. The IC"s extremely low noise floor at 2µV and its extremely low THD+N value of 0.06% at the rated power make the amplifier optimum.
