A revolutionary embedded algorithm in a new audio system from NXP Semiconductors N.V. (NASDAQ: NXPI) boosts the output power of micro speakers by over 5 times, vastly improving the sound quality of mobile devices. By driving over 2.6 watts RMS into micro speakers that have previously been limited to 0.5 W, the NXP TFA9887 IC will give mobile phones, portable music players and tablets much louder sound, deeper bass, and higher sound quality – without risking speaker damage. With a unique combination of safety features including adaptive excursion control and real-time temperature protection, the TFA9887 monitors speakers through a current-sensing amplifier and enables safe operation while working at near peak output at all times.
“Digital natives have come of age taking poor mobile sound quality for granted. As speakers have become smaller, the quiet, tinny sound we’ve come to associate with mobile devices has got even worse,” said Shawn Scarlett, director of marketing, mobile audio product line, NXP Semiconductors. “Our new audio system transforms the listening experience, enabling louder, richer sound quality from virtually any mobile device. The improvement is so striking that consumers, handset makers and operators will immediately hear the difference.”
