LM4734 3 Channel 20W Audio Power Amplifier

The LM4734 is a three channel audio amplifier capable of typically delivering 20W per channel of continuous average output power into a 4Ω or 8Ω load with less than 10% THD+N from 20Hz - 20kHz. The LM4734 has short circuit protection and a thermal shut down feature that is activated when the die temperature exceeds 150˚C. The LM4734 also has an under voltage.
