The LM4780 is fully protected utilizing Texas Instruments' Self Peak Instantaneous Temperature (°Ke) (SPi Ke TM) protection circuitry. SPi Ke provides a dynamically optimized Safe Operating Area (SOA). SPi Ke protection pletely safeguards the LM4780's outputs against over-voltage, undervoltage, overloads, shorts to the supplies or GND, thermal runaway and instantaneous temperature peaks. The advanced protection features of the LM4780 places it in a class above discrete and hybrid amplifiers. Each amplifier of the LM4780 has an independent smooth transition fade-in/out mute. The LM4780 can easily be configured for bridge or parallel operation for 120W mono solutions.
