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 with the non-isolated ’T’ package
and 30W per channel with the isolated ’TF’ package 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,
undervoltage, 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 2V and its
extremely low THD+N value of 0.06% at the rated power
make the LM4766 optimum for high-end stereo TVs or mini-
component systems.
