描述 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.
