Cx31993 Datasheet Fix Hot !exclusive! Jun 2026

After applying a "fix hot" solution, you need to verify success without a thermal camera.

If the dongle is hot and producing static with sensitive IEMs, the DAC might be working too hard on the high gain. cx31993 datasheet fix hot

~117 dB to 124 dB (depending on implementation). Total Harmonic Distortion (THD+N): -95dB. After applying a "fix hot" solution, you need

Buy a 3.5mm female-to-male adapter and solder a 75Ω, 1% metal film resistor in series with the tip (left) and ring (right) channels. Total Harmonic Distortion (THD+N): -95dB

Install a thermal pad between the chip and the aluminum chassis. High current draw from low impedance Use an inline impedance adapter plug (30Ω+).

To fix the thermal issues of the CX31993, we must first look at what the silicon is designed to do. The chip integrates a digital audio interface, a high-performance DAC, and a headphone amplifier into a tiny package. Key Technical Parameters Up to 32-bit / 384kHz PCM.

If you are using USB Audio Player Pro (UAPP) or similar high-fidelity apps, you can reduce the workload on the DAC.
