General Description: The LM4732 is a stereo audio amplifier capable of typically  delivering 50W per channel of continuous average output  power into a 4Ω or 8Ω 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.
