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鈩?load with less

than 0.1% (THD+N).

The performance of the LM4766, utilizing its Self Peak In-

stantaneous Temperature (藲Ke) (SPiKe

鈩?/div>

) 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.
