General 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. 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 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.

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)
