LM3886T/NOPB

The LM3886T/NOPB is a high performance stereo Audio Power Amplifier with mute capable of delivering 68W of continuous average power to a 4Ω load and 38W into 8Ω with 0.1% THD+N from 20Hz to 20kHz. The performance of the LM3886, 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, under-voltage, overloads, including shorts to the supplies, thermal runaway and instantaneous temperature peaks. This amplifier maintains an excellent signal-to-noise ratio of greater than 92dB with a typical low noise floor of 2.0µV. It exhibits extremely low THD+N values of 0.03% 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%.

• ≥92dB Signal-to-noise ratio
• An input mute function
• Output protection from a short to ground or to the supplies via internal current limiting circuitry
• Output overvoltage protection against transients from inductive loads
• Supply under-voltage protection, not allowing internal
• Green product and no Sb/Br
