NXP has introduced the third generation of smart amplifiers for smartphone audio systems

     NXP Semiconductors has introduced the TFA9897, a third-generation smart amplifier for smartphone audio systems. As the world's smallest smart amplifier solution, the TFA9897 will bring industry-leading speaker protection to all mobile phones at an affordable price. The launch of this product further demonstrates NXP's commitment to developing usable innovative solutions for the rapidly growing portable devices and wearables market.

     Since NXP released the world's first smart amplifier in 2012, the vast majority of leading smartphone manufacturers have adopted NXP Speaker protection solutions to improve the sound quality and volume of their devices. The strong demand for NXP smart amplifiers has enabled shipments of smart amplifiers to exceed 150 million units in just two and a half years.

     Worldwide, the rapid spread of smart phones, people are increasingly using mobile phones and tablets to play media, and always looking forward to better sound quality, which greatly stimulated the market demand for smart amplifiers. At the same time, phones are getting thinner and smaller, and the speaker is no longer located only on the back of the phone, which creates more acoustic problems for phone manufacturers. Therefore, the market demand for high-quality sound and intelligent amplifiers has also risen.

     Deheng Liu, Global Product Manager, Mobile Audio Solutions, NXP Semiconductors, said: "In the past year, smart amplifiers have become the standard feature of advanced smartphones. All 15 of the top smartphone manufacturers use some form of speaker protection. NXP is the leader in the smart amplifier market. Our customers include 13 of the top 15 Oems, including all 10 top Oems in China. Our solutions have been used in some of the most sought after phones on the market today, dramatically improving their sound quality."

     The TFA9897 is designed to deliver high-end performance to mainstream phones. The TFA9897 uses the latest version of NXP's industry-leading algorithms and is fully optimized for tiny speakers with an 8-ohm impedance. As with earlier smart amplifiers, the entire system is integrated on a single chip, including the CoolFuxDSP, a high-efficiency Class D amplifier with current sensing, and a DC-DC converter. As a one-stop, complete solution, the TFA9897 will be compatible and seamless with all platforms.

     All NXP intelligent power amplifier products provide all-in-one single-chip one-stop solution, the biggest advantage of this architecture is to avoid signal delay, can effectively provide protection, compared to other discrete solutions due to the delay between modules and reserve the margin, TFA9897 can provide higher equivalent power performance than the independent solution.

     NXP's integrated embedded protection algorithms do not require authorization from any third party. With professional tuning tools, designers can customize the audio quality and choose how to optimize the phone's performance. NXP Mobile Audio has the strongest customer support team in the world, who have many years of experience in the audio field, with a wealth of audio-related hardware and software expertise, and can provide the best support for designers to customize the design.
