The Cirrus Logic CS35L41 11-volt boosted Class D audio amplifier with DSP, complemented with Cirrus Logic’s SoundClear® Playback software, improves audio quality and increases the loudness of smartphone speaker output while protecting the speaker using both hardware and software techniques. Its advanced battery management system and predictive algorithms adapt to changing audio, speaker and battery conditions to minimize power consumption and battery current, without sacrificing audio performance. This new smart power amplifier also uses 55 nm process technology, the most advanced for this class of amplifiers, resulting in a tiny, 5.64 mm2 space-saving WLCS package. This is important to OEMs who want to include a two-speaker design, as well as pack in as many new features and functions as possible.

According to a SAR Audio Signal Chain IC forecast database from Q4 2018, market shipments for audio amplifiers have grown 3x from 2010 to 2018 due to the increasing shipments of audio playing devices, and also the increasing number of channels per device. “Amplifier shipment growth in the smart phone market is due not only to an increase in stereo sound in high-end phones but also the mid-tier market, defined as phones priced between $200 and $500,” said SAR Insight principal analyst, Peter Cooney. “We anticipate this growth to continue with an estimated increase from the 500 million amplifiers shipped into mid-tier phones in 2017, to almost 700 million by 2022.”

“More and more consumers are turning to their smartphone as a primary device for video streaming, gaming and listening to music – including using speakerphone or loudspeaker mode,” said Carl Alberty, vice president of Marketing, Cirrus Logic. “The sound quality from a phone using the CS35L41 is so impressive that you can leave your portable speaker behind and simply carry one device to enjoy media anywhere you go without compromise.”

The Cirrus Logic CS35L41 boosted amplifier delivers on the ‘big three’ requirements for mobile applications: enriched audio sound, efficient low-power management and a space-saving package. By incorporating features such as advanced battery management and predictive algorithms, the Cirrus Logic smart power amp increases the audio volume when in speakerphone mode, while reducing noise and power consumption, resulting in better battery life and improved talk times.
