On June 11, 2015, Uni-President Holdings, a leading semiconductor component distributor dedicated to the Asia-Pacific market, announced that its subsidiary Pinjia has launched NXP Smart Audio audio chips-TFA9890 / TFA9897. This IC can provide more than 3.6 W RMS power (previously limited to 0.5 W) for micro speakers, which will bring higher volume, thicker bass and better sound quality to mobile phones, portable music players and tablet computers without There is a risk of damaging the speakers. TFA9890 & TFA9897 integrates intelligent CoolFlux DSP, its function is to protect the horn safely and effectively even if it has been in the near-peak output state. Picture 1-NFA's TFA9890 / TFA9897 photo of the agent of UPU With the rise of smart phones, its lighter, thinner, smarter, and more power-saving features have brought great challenges to the improvement of mobile phone sound quality. The Smart Audio audio solution proposed by NXP Semiconductors, represented by UGA Pinjia, has brought a real change. The revolutionary embedded algorithm in NXP's new audio system can increase the output power of micro speakers by more than 5 times, thereby greatly improving the sound quality of mobile devices and effectively protecting the speakers.
