IC Audio AMP LM3886T 68W W/MuteMCM Part #: N-92F298  |  National Semiconductor Part #: LM3886T

SPiKe protection means that these parts are completely safeguarded at the output against over voltage, under voltage, overloads, including shorts to the 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 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%.

Power Output:
• 68W cont. avg. output power into 4ohm at ±28V VCC
• 38W cont. avg. output power into 8 ohm at ±28V VCC
• 50W cont. avg. output power into 8 ohm at ±35V VCC
• 135W instantaneous peak output power

Features:
• Signal-to-Noise Ratio = 92dB
• Input mute function
• Output protection from a short to ground or to the supplies via internal current limiting circuitry
• Output over-voltage protection against transients from inductive loads
• Supply under-voltage protection, not allowing internal biasing to occur when |VEE| + |VCC| = 12V, thus eliminating turn-on and turn-off transients
• 11-lead TO-220 package
• Wide supply range 20V~94V

Applications:
• Component stereo
• Compact stereo
• Self-powered speakers
• Surround-sound amplifiers
• High-end stereo Televisions
