STA540 Description
The STA540 is a 4-channel, class-AB audio amplifier designed for high-quality sound
applications. The STMicroelectronics STA540 has single-ended outputs with integrated short-circuit protection, thermal protection, and diagnostic functions. The amplifier STA540 is housed in the 15-pin Multiwatt ECOPACK? Pb-free package which is RoHS (2002/95/EC) compliant. What's more, the STA540 operates within ambient temperatures from 0 to 70°C and with power dissipation of 36000 mW.
