LM4733 3 Channel 30W Audio Power Amplifier with Mute September 2003 LM4733 3 Channel 30W Audio Power Amplifier with Mute General Description The LM4733 is a three channel audio amplifier capable of typically delivering 30W per channel of continuous average output power into a 4Ω or 8Ω 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 ±...
