Why Goodix

Overview

Goodix 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 the sound quality. The speaker boost firmware adaptation is managed by an external host processor for programmable smart amplifiers, therefore, our Non-DSP smart amplifier provides the same hardware performance as DSP-On-Chip smart amplifier with smaller die size. We offer the most advanced turn-key smart audio amplifier solution for getting the most from micro-speakers.
