DESCRIPTION
The LM1876 is a stereo audio amplifier capable of
delivering typically 20W per channel of continuous
average output power into a 4Ω or 8Ω load with less
than 0.1% THD+N.
Each amplifier 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 LM1876, 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
safeguarded at the output against overvoltage,
undervoltage, overloads, including thermal runaway
and instantaneous temperature peaks.
