Introduction
AI Translation
The STA540 is a 4-channel, class-AB audio amplifier designed for high quality sound applications. The amplifiers have single-ended outputs with integrated short-circuit protection, thermal protection and diagnostic functions. The chip is housed in the 15-pin Multiwatt ECOPACK Pb-free package which is RoHS (2002/95/EC) compliant.
