High-Performance HW & SW Solutions Deliver Premium Listening Experiences


Goodix offers the high-performance Class-D amplifier series, with the TFA9865 series standing out as the latest smart amplifier solution. This series sets a new benchmark for audio quality in mobile devices with a high 7 W peak output power and an ultra-low noise floor below 7 uV.

The TFA9865 series incorporates Goodix's proprietary first-generation CoolPWM technology, breaking away from traditional technology architectures with a pure digital path design and advanced energy efficiency management mechanisms, thereby delivering louder and clearer sound quality for mobile devices, and significantly extends device battery life. Goodix also collaborates with a renowned chip manufacturer to develop the first-of-its-kind and specially tuned 90 nm BCD process. Benefiting from advanced process and new digital architecture, the audio amplifier offers more flexibilities to customers’ applications, with dimensions of just 2.2 * 2.2 mm². Additionally, Goodix’s sophisticated SpeakerBoost(SPB) acoustic enhancement and protection algorithm helps to obtain the optimum performance for micro-speakers while simultaneously providing temperature and excursion protection.
