NXP Looks to Revolutionize Mobile Audio Performance with TFA9887 IC Audio System
NXP is out to change all that with the NXP TFA9887 IC audio system, which includes an embedded algorithm that can drive over 2.6W RMS through speakers that, up to this point, were only capable of 0.5W without causing damage to the speakers. The system uses adaptive excursion control, real-time temperature protection, and current-sensing amplification to intelligently maximize the audio performance while sensing and adjusting to aspects such as enclosure damage and battery voltage.
The NXP TFA9887 IC system is on a single chip and features NXP’s own CoolFlux audio DSP amp and DC-to-DC boost converter.
NXP calls the new micro driver “revolutionary”, and we surely hope it is. Any improvement to mobile device speaker performance is most welcome.
