LM4732 Stereo 50W Audio Power Amplifier

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 o.
