LM4765T
Overture Audio Power Amplifier Series Dual 30-Watt Audio Power Amplifier with Mute and Standby Modes
LM4765 Overture™
Audio Power Amplifier Series Dual 30W Audio Power
Amplifier with Mute and Standby Modes
General Description

The LM4765isa stereo audio amplifier capableof delivering
typically 30W per channelof continuous average output
power intoan8Ω load with less than 0.1% THD+N.
Each amplifier hasan independent smooth transition fade-
in/out mute anda power conserving standby mode which
canbe controlledby external logic.
The performanceof the LM4765, utilizingits Self PeakIn-
stantaneous Temperature (˚Ke) (SPiKe™) protection cir-
cuitry, placesitina class above discrete and hybrid amplifi-
ersby providingan inherently, dynamically protected Safe
Operating Area (SOA). SPiKe protection means that these
parts are safeguardedat the output against overvoltage,
undervoltage, overloads, including thermal runaway andin-
stantaneous temperature peaks.
