LM1876 Overture? Audio Power Amplifier Series
Dual 20W Audio Power Amplifier with Mute and Standby
Modes
General 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 fadein/
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.
