 Product Description

2 x LM3886T/NOPB Overture 68W Audiophile Quality Power Amplifier (mono)

The LM3886 is a high-performance audio power amplifier capable of delivering 68W of continuous average power to a 4Ω load and 38W into 8Ω with 0.1% THD+N from 20Hz–20kHz.

The performance of the LM3886, utilizing its Self Peak In- stantaneous Temperature ( í_Ke) (SPiKeTM) protection cir- cuitry, puts it in a class above discrete and hybrid amplifiers by providing an inherently, dynamically protected Safe Op- erating Area (SOA). SPiKe protection means that these parts are completely safeguarded at the output against ov- ervoltage, undervoltage, 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%.

Features

  • 68W cont. avg. output power into 4Ω at VCC = ±28V
  • 38W cont. avg. output power into 8Ω at VCC = ±28V
  • 50W cont. avg. output power into 8Ω at VCC = ±35V
  • 135W instantaneous peak output power capability n Signal-to-Noise Ratio 92dB
  • An 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
