) 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鈥檚 extremely low noise floor at 2碌V 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.
