LM4733
3 Channel 30W Audio Power Amplifier with Mute
General Description
The LM4733 is a three channel audio amplifier capable of
typically delivering 30W per channel of continuous average
output power into a 4
or 8
load with less than 10%
THD+N from 20Hz - 20kHz.
The LM4733 has short circuit protection and a thermal shut
down feature that is activated when the die temperature
exceeds 150C. The LM4733 also has an under voltage lock
out feature for click and pop free power on and off.
Each amplifier of the LM4733 has an independent smooth
transition fade-in/out mute.
The LM4733 has a wide operating supply range from
±
10V
-
±
32V allowing for lower cost unregulated power supplies to
be used.
The LM4733 amplifiers can easily be configured for bridge or
parallel operation for higher power and bi-amp solutions
