LM4780 Overture™ Audio Power Amplifier Series
Stereo 60W, Mono 120W Audio Power Amplifier with
Mute
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.
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.
