LM4766 Overture
Audio Power Amplifier Series Dual 40W Audio Power
Amplifier with Mute
General Description
The LM4766 is a stereo audio amplifier capable of delivering
typically 40W per channel of continuous average output
power into an 8
load with less than 0.1% (THD + N).
The performance of the LM4766, 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.
Each amplifier within the LM4766 has an independent
smooth transition fade-in/out mute that minimizes output
pops. The IC’s extremely low noise floor at 2 μV and its ex-
tremely low THD + N value of 0.06% at the rated power
make the LM4766 optimum for high-end stereo TVs or mini-
component systems.
