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.
