Stereo 50w Audio Power Amplifier With Mute - National Semiconductor

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. By National Semiconductor Corporation
