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

Ω or 8Ω 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 150˚C. 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.
