In a push for better sound quality and more output volume, leading mobile phone makers have been raising the internal voltage used to drive micro speakers -- from 3.3V through to 5V, and recently as high as 8V. This week at Mobile World Congress 2013 (Hall 7, Stand A111), NXP Semiconductors is launching its new TFA9890 speaker driver IC, which enables an unprecedented 9.5V boost voltage from an integrated DC/DC converter.
Increasing the voltage headroom in the audio driver IC prevents amplifier clipping and keeps sound quality high at maximum volume. The most powerful driver yet for micro speakers, the TFA9890 makes a clear improvement to the sound output and quality of mobiles, tablets, TVs and portable speakers. http://www.marketwire.com/press-relea...
