Troubleshooting the CX31993 Hi-Res DAC: Heat Issues and Datasheet Fixes Any "hot fixes" should be approached with caution
The Conexant CX31993 has become ubiquitous as a budget-friendly USB-C to 3.5mm DAC dongle. Its subjective reputation, however, is polarized: many praise its detail retrieval, while others complain it sounds “hot,” “glassy,” or “fatiguing.” This harshness is not a flaw in the core DAC architecture—it is a predictable consequence of and missing post-DAC filtering , as hinted at in the component’s reference design.
The official Conexant (now Synaptics) CX31993 datasheet lists the chip as a "high-performance, low-power audio codec." The keyword is low power . The sheet claims a typical current consumption of for the digital-to-analog conversion.
To fix the thermal issues of the CX31993, we must first look at its architecture and deployment environment, which explains why it generates noticeable heat. 1. High-Performance Audio Processing
