: It is noted for running cool and having minimal impact on a smartphone's battery life, often consuming only about 2% extra battery per hour of use.
Up to 32bits/384kHz . This capability allows for processing high-resolution audio files far beyond CD quality (16bit/44.1kHz).
The (often branded under Conexant or CX-Pro) has established itself as one of the most popular, high-value audio DAC (Digital-to-Analog Converter) chips in the budget portable audio market. It is frequently found in affordable USB-C to 3.5mm "dongles" that have replaced traditional headphone jacks on modern smartphones, laptops, and tablets.
