Texas Instruments - LM4780TA Overture™ Audio Power Amplifier Series Stereo 60W, Mono 120W IC
The LM4780 is a stereo audio amplifier capable of typically delivering 60W per channel of continuous average output power into an 8 Ohms load with less than 0.5% THD+N from 20Hz - 20kHz. The LM4780 is fully protected utilizing Texas Instruments' Self Peak Instantaneous Temperature (Degree Ke) (SPiKeTM) protection circuitry. SPiKe provides a dynamically optimized Safe Operating Area (SOA). SPiKe protection completely safeguards the LM4780'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 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.
