The CX31993 is a designed for portability and power. According to the datasheet and manufacturer specifications, it offers:
For USB-C iPhones or Android devices, is the main problem.
The CX31993 features an automatic impedance detection circuit. It measures the resistance of the connected headphone upon insertion to switch between Low-Gain (for IEMs) and High-Gain (for full-sized headphones) modes.
Conexant CX31993 is a high-performance USB Type-C digital-to-analog converter (DAC) chip widely used in ultra-portable "dongle" DACs to upgrade mobile audio. It is known for delivering clean, transparent sound with a significant improvement in resolution over standard phone outputs.
