Description

The LM4734 is a three channel audio amplifier capable of typically delivering 20W per channel of continuous average output power into a 4 or 8 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 lock out feature for click and pop free power on and off. Each amplifier of the LM4734 has an independent smooth transition fade-in/out mute and a power conserving standby mode. The mute and standby modes can be controlled by external logic.

The LM4734 has a wide supply operating supply range from ±10V - ±30V allowing for lower cost unregulated power supplies to be used.

The LM4734 can easily be configured for bridge or parallel operation for higher power and bi-amp solutions.
