LM4782 Description

The LM4782 is a three channel audio amplifier capable of typically delivering 25W per channel of continuous average output power into an 8 load with less than 0.5% THD+N from 20Hz - 20kHz.

The LM4782 is fully protected utilizing National's Self Peak Instantaneous Temperature (°Ke) (SPiKe^TM) protection circuitry. SPiKe provides a dynamically optimized Safe Operating Area (SOA). SPiKe protection completely safeguards the LM4782's outputs against over-voltage, under-voltage, overloads, shorts to the supplies or GND, thermal runaway and instantaneous temperature peaks. The advanced protection features of the LM4782 places it in a class above discrete and hybrid amplifiers.

Each amplifier of the LM4782 has an independent smooth transition fade-in/out mute and a power conserving standby mode. The mute and standby modes can be controlled by external logic.

The LM4782 can easily be configured for bridge or parallel operation for higher power and bi-amp solutions.
