When using speaker mode to play music, podcast, hold video conference, watch movies and play games, cirrus logic cs35l45 booster amplifier creates a new audio enjoyment for consumers.

Austin, Texas, March 25, 2021: as consumers increasingly use the built-in speakers of mobile phones to enjoy music, podcast, watch movies and play games, cirrus logic (NASDAQ: crus) is launching its latest flagship cs35l45 booster amplifier, which can provide richer, more reliable and more reliable services for smart phones, tablet computers and mobile game devices More immersive audio experience. Cirrus logic’s cs35l45 smart power amplifier enables speakers to operate in higher amplitude regions for high peak loudness and improved dynamic range, providing more impact timbre and bass accuracy, lower noise and noise, and better tone balance at all volume levels, helping mobile device manufacturers push audio performance to a new industry benchmark.

Cirrus logic cs35l45 is a 15V intelligent boost class D audio amplifier with DSP, which can be easily integrated into the stereo or multi speaker playback solutions of the next generation of flagship mobile devices, and can improve the performance of midrange devices without upgrading the speakers. It also features speaker protection and adaptive battery management to drive higher output power under all battery conditions, with a 30% increase in peak loudness compared to cirrus logic’s previous flagship boost amplifier.

Carl alberty, vice president of mixed signal products at cirrus logic, said: “in order to meet consumers’ demand for richer and more immersive audio experience, smart phone OEMs are integrating more and more powerful speakers into the next generation of devices. Cirrus logic’s cs35l45 flagship boost amplifier improves the audio quality of micro speakers in these mobile devices, providing greater loudness, dynamic range, and higher bass and tone balance, while protecting speakers and extending battery life. “

According to a new user survey by sarinsight & consulting, 40% of respondents have increased their use of speaker mode in the past 12 months. The global survey shows that during the COVID-19, as more and more people are at home, they use more mobile phone speakers to watch and share videos on social media, video calls and listen to podcasts or music while handling multitasking, or just to create a better atmosphere. All these factors make consumers eager for better sound quality from smart phones.

Louder, improved dynamic range and longer battery life

With 7W output power and 15V dynamic boost, cs35l45 intelligent power amplifier can achieve higher peak power at all frequencies, so as to achieve better tone balance, better dynamic effect, larger space range and timbre at all volume levels. Due to its ability to draw a large amount of current from the battery, cs35l45 is system aware, with built-in battery current monitoring and voltage monitoring that can provide high output power, but only when the source audio content needs to be reproduced. The cs35l45 amplifier’s proprietary adaptive battery management technology helps to “anticipate” sudden audio spikes, thereby protecting the battery, preventing fluctuations and clipping, and maximizing audio performance at all volume levels without noise.

The Y-bridge output driver on the cs35l45 achieves higher efficiency in handset mode and speaker mode, thereby extending battery life. The next generation of more accurate speaker protection algorithm can push the speaker to the maximum limit while keeping it within the safety limit. DSP on chip firmware features include equalization and psychoacoustic enhancement to maximize the performance of small speakers. This will bring the flagship acoustic performance of stereo smart phones, which can achieve the loudness and sound quality of portable speakers, and still save energy.

supply commodity

Cirrus logic cs35l45 intelligent power amplifier is now available in bulk, with commercial grade 0.4mm spacing, 36 ball WLCSP package, and working temperature range from – 40C to + 85C.
