LM4730
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
- 20k Hz. 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. The LM4730 has a wide operating supply range from +/-10V
- +/-25V allowing for lower cost unregulated power supplies to be used.
