LM4781 Product details

Description

The LM4781 is a three channel audio amplifier capable of typically delivering 35W per channel of continuous average output power into an 8Ω load with less than 0.5% THD+N from 20Hz - 20kHz.

Features

of the LM4781 places it in a class above discrete and hybrid amplifiers. Each amplifier of the LM4781 has an independent smooth transition fade-in/out mute. The LM4781 can easily be configured for bridge or parallel operation for higher power and bi-amp solutions.
