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.”
