STA540
4 x 13 W dual/quad power amplifier
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.
This amplifier is really one of the most versatile amplifiers ever, configurable like:

– 2x 34 W into 8 Ω at 22 V, 1 kHz, 10% THD
– 2x 24 W into 4Ω at 14.4 V, 1 kHz, 10% THD
– 2x 15 W into 8 Ω at 16 V, 1 kHz, 10% THD
– 4x 13 W into 2 Ω at 15 V, 1 kHz, 10% THD
– 4x 11 W into 4 Ω at 18 V, 1 kHz, 10% THD
– 4x 7 W into 4 Ω at 14.4 V, 1 kHz, 10% THD
Serious thought has also been given to protection.
Protection
■ Output AC/DC short circuit
■ Soft short-circuit check at turn-on
■ Thermal cutoff/limiter to prevent chip from overheating
■ High inductive loads
■ ESD
