The LM3886 is a high-performance audio power amplifier integrated circuit (IC) manufactured by Texas Instruments. Here’s an overview of its features and specifications:

  • Type: Audio Power Amplifier IC
  • Power Output: Capable of delivering up to 68 watts of continuous average power into an 8-ohm load with a ±35V supply voltage.
  • Configuration: Provides a single-channel audio amplifier suitable for mono applications. However, it can be configured for stereo applications by using two LM3886 ICs.
  • High Performance: Known for its high-performance characteristics, including low distortion, low noise, and high signal-to-noise ratio (SNR), ensuring accurate and clear audio reproduction.
  • Wide Bandwidth: Offers a wide bandwidth, allowing for accurate amplification of audio signals across a broad frequency range.
  • Protection Features: Includes built-in protection features such as over-temperature shutdown and output DC offset detection, safeguarding the amplifier and connected speakers.
  • Voltage Supply Range: Typically operates from a dual supply voltage, with recommended supply voltages ranging from ±20V to ±35V.
  • Package: It’s commonly available in TO-220 and TO-220FP packages, which are suitable for heat sinking to dissipate heat generated during operation.
  • Temperature Range: It typically operates across a moderate temperature range, often from 0°C to 70°C.

The LM3886 is widely used in high-quality audio amplifier designs where high power output, low distortion, and reliable performance are essential, such as home audio systems, studio monitors, powered speakers, and guitar amplifiers. Its robust design and comprehensive protection features make it a popular choice among audio enthusiasts and professionals for building high-performance audio amplifiers.
