Product Introduction

Overview

The LM4766T/LF15, produced by Texas Instruments, is a high-performance stereo audio power amplifier. This device is part of the Overture™ Audio Power Amplifier Series and is designed to deliver superior audio quality with robust protection features. The LM4766 is capable of delivering typically 40W per channel with the non-isolated NDL package and 30W per channel with the isolated NDB package into an 8Ω load with less than 0.1% Total Harmonic Distortion plus Noise (THD+N). It features a wide supply range of 20V to 78V and includes advanced protection circuitry such as over-voltage, under-voltage, and thermal protection, ensuring reliable operation in various audio applications.

Key Features

  • SPiKe Protection: Safeguards against overvoltage, undervoltage, overloads, and instantaneous temperature peaks.
  • Quiet Fade-In/Out Mute Mode: Minimizes output pops during mute transitions.
  • Minimal External Components: Reduces the need for additional components.
  • Wide Supply Range: Operates from 20V to 78V.
  • Thermal Protection: Shuts down at 165°C and restarts at 155°C to prevent thermal stress.
  • Over-Voltage and Under-Voltage Protection: Limits output current and prevents DC output spikes.

Applications

  • High-End Stereo TVs
  • Component Stereo Systems
  • Compact Stereo Systems
  • Bridged Amplifier Configurations

Q & A

  1. What is the maximum output power of the LM4766? The LM4766 can deliver up to 40W per channel with the non-isolated NDL package and up to 30W per channel with the isolated NDB package.
  2. What is the typical THD+N of the LM4766 at 1kHz? The typical THD+N at 1kHz is 0.009%.
  3. What is the supply voltage range for the LM4766? The supply voltage range is from 20V to 78V.
  4. Does the LM4766 have thermal protection? Yes, it has a thermal protection scheme that shuts down the device at 165°C and restarts it at 155°C.
  5. How does the mute function work on the LM4766? The mute function is activated by drawing more than 0.5mA from each mute pin, which can be controlled using a switch and resistor.
  6. What types of protection does the LM4766 offer? The LM4766 offers SPiKe protection, over-voltage protection, under-voltage protection, and thermal protection.
  7. Can the LM4766 be used in bridged amplifier configurations? Yes, the LM4766 can be used in bridged amplifier configurations, which can theoretically provide four times the output power compared to single-ended configurations.
  8. What is the ESD susceptibility of the LM4766? The ESD susceptibility is 3000V.
  9. What is the storage temperature range for the LM4766? The storage temperature range is from −40°C to +150°C.
  10. How does the under-voltage protection work on the LM4766? The under-voltage protection allows the power supplies to reach their full values before turning on the amplifier, preventing DC output spikes.
