LM4781 Datasheet 3-channel 35w Audio Power Amplifier

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM4781 Overture™ Audio Power Amplifier Series 3 Channel 35W Audio Power Amplifier with Mute August 2003 LM4781 Overture™ Audio Power Amplifier Series 3 Channel 35W Audio Power Amplifier with.

General Description

The LM4781 is a three channel audio amplifier capable of typically delivering 35W per channel of continuous average output power into an 8Ω load with less than 0.5% THD+N from 20Hz - 20kHz.

The LM4781 is fully protected utilizing National’s Self Peak Instantaneous Temperature (˚Ke) (SPiKeTM) protection circuitry.

SPiKe provides a dynamically optimized Safe Operating Area (SOA).

Key Features

  • of the LM4781 places it in a class above discrete and hybrid amplifiers. Each amplifier of the LM4781 has an independent smooth transition fade-in/out mute. The LM4781 can easily be configured for bridge or parallel operation for higher power and bi-amp solutions.
