LM4700
Overture Audio Power Amplifier Series
30W Audio Power Amplifier with
Mute and Standby Modes
General Description
The LM4700 is an audio power amplifier capable of deliver-
ing typically 30W of continuous average output power into an
8
load with less than 0.1% (THD + N).
The LM4700 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 LM4700, 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 completely safeguarded at the output against over-
voltage, undervoltage, overloads, including thermal runaway
and instantaneous temperature peaks.
