Linear and digital high-efficiency audio power amplifiers with start-stop
and hybrid-vehicle compatibility
ST is world leader in automotive
audio power amplifiers, and
offers solutions for each market
segment. ST is also committed
to environment protection
and was the first company to
design audio amplifiers with the
specific target of allowing car
makers to decrease exhaust,
fuel consumption and vehicle
weight.
Every new power amplifier from
ST is now compatible with the
most recent technologies for
green vehicles, such as
start-stop and hybrid
technologies, and embeds
advanced high-efficiency
solutions.
Key features
•
Compatibility with start-stop and
Digital families
•
Class D high efficiency with
hybrid-vehicle battery profiles: 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 efficiency with up to
optimized BOM
•
Class SBi high efficiency with up to
50% less power dissipation
compared to class AB
Key benefits
•
Low power dissipation with high
25% less power dissipation
compared to class AB
(actual measurements)
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
