Introduction to TFA9879
Digital-in mono Class D audio amplifier with feedback loop for low-power applications.
NXP smart amplifier is a high efficiency boosted Class-D audio amplifier with a sophisticated SpeakerBoost acoustic enhancement and Protection algorithm in on-Chip DSP with temperature and excursion protection. The internal adaptive DC-to-DC converter raises the power supply voltage, providing ample headroom for major improvements in sound quality.
Non-DSP smart amplifier provides the same hardware performance as DSP-On-Chip smart amplifier with smaller die size. The speaker boost firmware adaptation is managed by an external host processor for Programmable smart amplifiers.
Our smart audio amplifiers offer an advanced solution to this conflict. They offer a turn-key solution for getting the most from micro-speakers.End-User Benefits
