LM4732 Features

  • Low external component count
  • Quiet fade-in/out mute mode
  • Wide supply range: 20V - 80V

LM4732 Description

    The LM4732 is a stereo audio amplifier capable of typically delivering 50W per channel of continuous average output power into a 4 or 8 load with less than 10% THD+N from 20Hz - 20kHz.

    The LM4732 has short circuit protection and a thermal shut down feature that is activated when the die temperature exceeds 150°C. The LM4732 also has an under voltage lock out feature for click and pop free power on and off.

    Each amplifier of the LM4732 has an independent smooth transition fade-in/out mute.

    The LM4732 has a wide operating supply range from +/-10V - +/-40V allowing for lower cost unregulated power supplies to be used.

    The LM4732 amplifiers can easily be configured for bridge or parallel operation for 100W mono solutions.
