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.
