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

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

25% less power dissipation

compared to class AB

(actual measurements)

Digital families

• Class D high efficiency with

optimized BOM

• Class SBi high efficiency 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
