LM4730 Stereo 14W Audio Power Amplifier with Mute and Standby Modes OBSOLETE LM4730 October 26, 2009 Stereo 14W Audio Power Amplifier with Mute and Standby Modes General Description The LM4730 is a stereo audio amplifier capable of delivering typically 14W per channel of continuous average output power into a 4Ω or 8Ω load with less than 10% THD+N from 20Hz - 20kHz. Each amplifier has an independent smooth transition fade-in/ out mute and a power conserving standby mode which can be controlled by external logic. The LM4730 has short circuit protection and a thermal shut down feature that is activated when the die temperature exceeds 150°C. The LM4730 also has a under voltage lock out feature for click and pop free power off and on.
