Analog Class D Amplifier with Boost Converter and Proprietary
Embedded Software Delivers Louder, Clearer Audio Output in LG G3
Smartphone’s Class-Leading 1W Speaker
AUSTIN, Texas--(BUSINESS WIRE)--
Cirrus Logic, Inc. (NASDAQ: CRUS), a market leader in low-power audio
applications, announced that it is shipping its CS35L32 Class D
amplifier into LG’s new flagship smartphone, the LG G3.

The CS35L32 high-performance speaker amplifier solution includes
advanced speaker amplifier hardware accompanied by proprietary, adaptive
real-time embedded software, providing speaker monitoring and protection
in addition to sound enhancement to ensure optimized audio performance
and quality.
The CS35L32’s performance enhances the consumer experience by delivering
30 percent more power to a speaker without compromising sound quality or
reliability. Speakers used in small portable audio applications such as
smartphones and tablets typically have physical and thermal limitations
to drive full-range signals at loud volumes. As a result, speaker output
performance is usually restricted to lower power, which limits overall
audio performance. The CS35L32 overcomes these challenges with an
integrated boost converter, integrated voltage and current monitoring
and reporting circuitry to enable speaker protection, bass enhancement
and improved linearity.
The CS35L32 drives the LG G3’s speaker power 30 percent higher – and
with a larger audio dynamic range – than typical Class D amplifiers that
don’t provide speaker protection and voltage boosting capability.
“Cirrus Logic’s technology leadership in mobile Class D amplifier
products and our ability to deploy proprietary algorithms into the
applications processor for protecting speakers and enhancing sound
quality were both important factors in LG’s decision to use the CS35L32
for their flagship G3 smartphone,” said Carl Alberty, director of
marketing, Cirrus Logic. “As we complement our 5V boosted Class D
amplifier product line with higher-voltage capability in upcoming new
products, we’re excited to offer our smartphone and tablet customers an
even louder, higher-quality audio solution that delivers great user
experiences.”
