STA540

音频放大器 4-CH AB Audio AMP 4 X 13 W Dual/Quad 4 x 13 W dual/quad power amplifier

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.

Protection STA540

■ Output AC/DC short circuit

■ Soft short-circuit check at turn-on

■ Thermal cutoff/limiter to prevent chip from overheating

■ High inductive loads

■ ESD
