Understanding the CX31993: High-Fidelity Audio in a Tiny Package
(commonly used in budget USB-C to 3.5mm adapters), here is a summary of the datasheet parameters CX31993 USB-C DAC Specifications (Often paired with 4-8 strands of sterling silver cable) Interface: USB-C to 3.5mm Audio Jack DAC Sampling Rate: Up to 32bits/384KHz (PCM) DSD Support: SNR (Signal-to-Noise Ratio): DNR (Dynamic Range): THD+N (Distortion): Output Thrust/Power: ~65mW (approximate output) Compatibility:
The datasheet figures reveal a limitation: the CX31993 is optimized for and low-impedance headphones. With a max output of 1.2Vrms, it struggles to drive high-impedance studio headphones (e.g., Sennheiser HD600 series at 300Ω). On a 300Ω load, the power output drops to roughly 0.5mW, resulting in low volume.
