LM1876 Overture

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 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 In-

stantaneous Temperature (˚Ke) (SPiKe

cuitry, places it in a class above discrete and hybrid amplifi-

ers 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 in-

stantaneous temperature peaks.
