The WCD9341 is a System-on-Chip (SoC) audio codec designed for portable and mobile devices, such as smartphones, tablets, and laptops. The chip provides a comprehensive audio solution, integrating multiple functions including analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and audio processing capabilities.
Many users expected native DSD via I²S – not possible. The codec internally converts DoP back to 1-bit stream before analog stage. wcd9341 datasheet
