General Description
The LM4701 is an audio power amplifier capable of delivering typically 30W of continuous average output
power into an 8Ohm load with less than 0.1% THD+N.
The LM4701 has an independent smooth transition fade-in/out mute and a power conserving standby mode
which can be controlled by external logic.
The performance of the LM4701, utilizing its Self Peak Instantaneous Temperature (°Ke) (SPiKe)
protection circuitry, places it in a class above discrete and hybrid amplifiers by providing an inherently,
dynamically protected Safe Operating Area (SOA). SPiKe protection means that these parts are completely
safeguarded at the output against overvoltage, undervoltage, overloads, including thermal runaway and
instantaneous temperature peaks.
