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.
