Product overview

Description

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.
