LM4733TA Features

  • Low external component count
  • Quiet fade-in/out mute mode
  • Wide supply range: 20V - 64V

LM4733TA Description

    The LM4733 is a three channel audio amplifier capable of typically delivering 30W per channel of continuous average output power into a 4 or 8 load with less than 10% THD+N from 20Hz - 20kHz.

    The LM4733 has short circuit protection and a thermal shut down feature that is activated when the die temperature exceeds 150°C. The LM4733 also has an under voltage lock out feature for click and pop free power on and off.

    Each amplifier of the LM4733 has an independent smooth transition fade-in/out mute.

    The LM4733 has a wide operating supply range from ±10V - ±32V allowing for lower cost unregulated power supplies to be used.

    The LM4733 amplifiers can easily be configured for bridge or parallel operation for higher power and bi-amp solutions
