LM4732
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 - 20k Hz. 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.
