LM4730
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 4
or 8 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 150C. 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.
