The GC1219 device has combined Goodix’s high-fidelity, high-efficiency hardware audio codec with integrated high performance DSP. The GC1219 sets a new benchmark for its flexibility, ease-of-use, performance, and energy efficiency.
The GC1219 has integrated 2 stereo (4 inputs) Analog-to-Digital Converters (ADCs) and a stereo Digital-to-Analog Converter (DAC) with a capless headphone driver. This chip is an ideal smart codec for a number of battery-powered wireless audio applications, like Bluetooth True Wireless Stereo (TWS) headset, Bluetooth stereo headset, and voice trigger applications.
