LM3886T/NOPB | Texas Instruments

Audio Power Amplifier, LM3886T/NOPB, Texas Instruments

The LM3886T/NOPB is a high-performance audio power amplifier capable of delivering 68 W of continuous average power to a 4 Ω load and 38 W into 8 Ω with 0.1% THD+N from 20 Hz-20 kHz. The performance of the LM3886T/NOPB is enhanced by its Self Peak Instantaneous Temperature (°Ke) (SPiKe) protection circuitry, which provides a dynamically protected Safe Operating Area (SOA). SPiKe protection safeguards the output against overvoltage, undervoltage, overloads-including shorts to the supplies-thermal runaway, and instantaneous temperature peaks. The LM3886T/NOPB maintains an excellent signal-to-noise ratio of greater than 92 dB with a typical low noise floor of 2.0 µV. It exhibits extremely low THD+N values of 0.03% at the rated output into the rated load across the audio spectrum, and provides excellent linearity with an IMD (SMPTE) typical rating of 0.004%.
