GC1229 - Low Power Smart Codec IC

Overview

The GC1229 device has combined Goodix’s high-fidelity, high-efficiency hardware audio codec with integrated high performance DSP. The GC1229 sets a new benchmark for flexibility, ease-of-use, performance, and energy efficiency.

The GC1229 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 many battery-powered wireless audio applications, such as Bluetooth True Wireless Stereo (TWS) headset, Bluetooth stereo headset, and voice trigger applications.
