LM4733
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
- 20k Hz. 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 ± 10V
- ± 32V allowing for lower cost unregulated power supplies to be used. The LM4733 amplifiers can easily be configured for bridge or parallel operation for higher power and bi-amp solutions
