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 4
or 8
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
) Protection Cir-
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, un-
dervoltage, overloads, including thermal runaway and in-
stantaneous temperature peaks.
