ST is world leader in automotive audio power amplifers, and offers solutions for each market segment. ST is also committed to environment protection and was the frst company to design audio amplifers with the specifc target of allowing car makers to decrease exhaust, fuel consumption and vehicle weight.
Every new power amplifer from ST is now compatible with the most recent technologies for green vehicles, such as start-stop and hybrid technologies, and embeds advanced high-effciency solutions.

KEY FEATUREs
• Compatibility with start-stop and hybrid-vehicle battery profles: the engine stops and restarts without any interruption or noise on the audio
• Full protection against any misconnection
• Full digital diagnostics
• High noise-injection immunity
• Automotive-grade EMC performances
• MOSFET output power
• Superior audio performances

Analog family
• Class SB high effciency with up to 25% less power dissipation compared to class AB (actual measurements)

Digital families
• Class D high effciency with optimized BOM
• Class SBi high effciency with up to 50% less power dissipation compared to class AB

Key benefits
• Low power dissipation with high output power
• Smaller heatsink allowing smaller and lighter applications
• Contribution to emission reductions and environment protection
• Lower application cost compared to equivalent solutions (especially for class D)
• Compatibility with existing products, so direct replacement is possible with minor redesign

targeteD applications
• Head units
• Boosters
• Automotive sound systems
