NXP Semiconductors introduced the third-generation smart power amplifier-TFA9897, which is suitable for smartphone audio systems. As the world's smallest smart power amplifier solution, TFA9897 will enable industry-leading speaker protection solutions to benefit all mobile phones at an affordable price. NXP is making every effort to develop available innovative solutions for the fast-growing portable device and wearable device market. The launch of this product further demonstrates NXP's determination.
Since NXP released the world's first smart power amplifier in 2012, most leading smartphone manufacturers have adopted NXP speaker protection solutions to improve the sound quality and volume of their devices. The strong demand for NXP's smart power amplifiers has allowed the shipment of smart power amplifiers to exceed 150 million in just two and a half years.
Globally, smart phones are rapidly becoming popular, and people are increasingly using mobile phones and tablets to play media, and always look forward to better sound quality, which greatly stimulates the market demand for smart power amplifiers. At the same time, mobile phones have become more and more thin and compact, and the speaker location is no longer only on the back of the phone, which brings more acoustic problems to the phone manufacturer. Therefore, the market's demand for high-quality sound and smart power amplifiers has also risen.
Deheng Liu, Global Product Manager, Mobile Audio Solutions, NXP Semiconductors, said: "In the past year, smart amplifiers have become a standard feature in advanced smartphones. All 15 top smartphone manufacturers have used some form of speaker protection. Pu is the leader in the smart power amplifier market. Our customers include 13 of all 15 top OEMs, including all 10 top OEMs in China. Our solutions have been used in the most sought after market today Some mobile phones have greatly improved their sound quality."
TFA9897 is designed to provide high-end performance for mainstream mobile phones. TFA9897 uses the latest version of NXP’s industry-leading algorithm and is fully optimized for miniature speakers with an impedance of 8 ohms. Like the smart power amplifier released earlier, the entire system is integrated on a single chip, including CoolFuxDSP, a high-efficiency Class D amplifier with current sensing function, and a DC-DC converter. As a one-stop complete solution, TFA9897 will be compatible with all platforms and seamlessly connect.
All NXP smart power amplifier products provide All-in-One single-chip one-stop solutions. The biggest advantage of this architecture is that it avoids signal delay and can effectively provide protection. Compared with other discrete solutions due to the delay between modules With the reserved margin, TFA9897 can provide higher equivalent power performance than discrete solutions.
NXP's integrated embedded protection algorithm does not require any third-party authorization. With the help of professional tuning tools, designers can customize the audio quality and choose how to optimize the performance of the phone. NXP's mobile audio department has the world's strongest customer support team. They have many years of experience in the audio field, and have rich audio-related software and hardware expertise, which can provide designers with the most powerful support for customized designs.
