The feedback-controlled excursion protection algorithm enables the TFA9890 -- a single chip that includes NXP's CoolFlux DSP, a Class-D amplifier with current sensing, and a DC-to-DC converter -- to provide nearly twice as much power into 8-ohm speakers, with sound output typically 6-12 dB higher than the TFA9887. In addition to increasing the speaker volume, the DC-to-DC converter's 9.5V boost voltage improves sound quality by increasing voltage headroom and eliminating amplifier clipping.
Other circuits and algorithms which improve sound quality include an advanced clip avoidance algorithm, which monitors audio performance and prevents clipping even when the power supply begins to sag. Bandwidth extension increases the low frequency response well below speaker resonance. Further, the intelligent DC-to-DC boost converter in the TFA9890 also prevents the audio system from causing battery under-voltage issues for the mobile device. The advanced, embedded algorithms require no separate licensing and allow designers to customize their audio sound quality and choose how to optimize the phone's performance.
The TFA9890 is now sampling with lead customers and will be released in Q2 2013. A demo showing the performance of the TFA9890 is featured this week at the NXP booth at Mobile World Congress (Hall 7, A111), and can also be viewed here: http://youtu.be/oaUtrpALyi8
