LM4732
Stereo 50W Audio Power Amplifier with Mute
General Description
The LM4732 is a stereo audio amplifier capable of typically
delivering 50W per channel of continuous average output
power into a 4
or 8
load with less than 10% THD+N from
20Hz - 20kHz.
The LM4732 has short circuit protection and a thermal shut
down feature that is activated when the die temperature
exceeds 150C. The LM4732 also has an under voltage lock
out feature for click and pop free power on and off.
Each amplifier of the LM4732 has an independent smooth
transition fade-in/out mute.
The LM4732 has a wide operating supply range from +/-10V
- +/-40V allowing for lower cost unregulated power supplies
to be used.
The LM4732 amplifiers can easily be configured for bridge or
parallel operation for 100W mono solutions.
