The LM4782 is fully protected utilizing National's Self Peak Instantaneous Temperature (Ke) (SPiKeTM) protection circuitry. SPiKe provides a dynamically optimized Safe Operating Area (SOA). SPiKe protection completely safeguards the LM4782's outputs against over-voltage, under-voltage, overloads, shorts to the supplies or GND, thermal runaway and instantaneous temperature peaks. The advanced protection features of the LM4782 places it in a class above discrete and hybrid amplifiers.
