Product overview
Overview
Description
The LM4780 is a stereo audio amplifier capable of typically delivering 60W per channel of continuous average output power into an 8Ω load with less than 0.5% THD+N from 20Hz - 20kHz.
The LM4780 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 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.
Features · SPiKe Protection· Low external component count· Quiet fade-in/out mute mode· Wide supply range: 20V - 84V· Signal-to-Noise Ratio ≥ 97dB (ref. to PO = 1W) Applications · Audio amplifier for component stereo· Audio amplifier for compact stereo· Audio amplifier for self-powered speakers· Audio amplifier for high-end and HD TVs
