Free - Cx31993 Datasheet Fix Hot
The has become a darling in the mobile audiophile world. For less than $10, this tiny USB-C DAC chip delivers surprisingly high-fidelity audio—supporting PCM up to 384kHz and DSD256. It rivals dongles costing five times as much.
However, many hardware builders, DIY enthusiasts, and Audiophiles troubleshooting their setups run into a common roadblock: finding an official Go to product viewer dialog for this item.
Open the dongle housing and apply a small piece of 0.5mm high-conductivity thermal silicone pad directly over the CX31993 chip. Ensure it firmly presses against the metal outer shell when reassembled, turning the entire casing into a passive heatsink. Firmware and Software Fixes: Power Management cx31993 datasheet fix hot

However, many mobile and desktop users frequently report a troubling issue: the DAC runs excessively hot The has become a darling in the mobile audiophile world
Users often report higher temperatures when connected to a PC compared to a phone, likely due to the PC's more robust (and sometimes noisier) USB power supply. Top Fixes for Overheating and Noise
The chip often struggles with power management when connected to USB 2.0 ports or devices, leading to heat accumulation. Firmware and Software Fixes: Power Management According to
The DAC chip is a common budget-friendly component often paired with the MAX97220 amplifier in portable USB-C dongles. While a formal, public "datasheet" from the manufacturer (Conexant/Synaptics) is notoriously difficult to find, community documentation and real-world testing highlight a recurring issue where these devices run excessively hot and produce static. Why it gets "Hot"
Remember: A warm DAC is a working DAC. A hot DAC is a poorly implemented one. Now you have the power to fix it.
Playing high-bitrate files like DSD can push the DAC to temperatures around The "Fix" (Community-Sourced)
