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 TI's Self Peak Instantaneous Temperature (°Ke) (SPiKe) protection circuitry.

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