LM4781 Overview
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 TI's Self Peak Instantaneous Temperature (°Ke) (SPiKe) protection circuitry. SPiKe provides a dynamically optimized Safe Operating Area (SOA).
