Cx31993 Datasheet Fix Hot -

(5.25V – 3.3V) × 0.088A = 0.17W extra heat. In a QFN package (θja=52°C/W), that's a 9°C rise before considering any audio load.

Ensure the dongle is not trapped under a phone case or in a tight pocket while in use. Allowing airflow around the metal chassis can significantly reduce surface temperature. Conclusion: Is the Heat a Problem?

The CX31993 remains one of the best value DAC chips on the market, offering exceptional 32-bit/384kHz quality in a tiny footprint. However, the frustrations around "hot plugging" are real and widespread. cx31993 datasheet fix hot

Based on modifications done by hobbyists (referenced by the community and a specific CXADC wiki), here is how you cool it down:

Class G (efficient power switching based on signal level). Total Harmonic Distortion (THD+N): 0.0003%. Fix: Why is it running "Hot"? Allowing airflow around the metal chassis can significantly

According to the limited available technical data and community reviews from platforms like Head-Fi : : >128dB Dynamic Range : >120dB Output Power : ~65mW @ 32Ω Decoding : Up to 32bits/384KHz Despite its small size, the

Warning: Requires micro-soldering. Warranty void.

The heat has no place to dissipate, making the dongle chassis feel hot to the touch.

If your issues extend beyond heat to include choppy, crackling, or distorted audio, there are specific audio-related fixes to try:
