Cx31993 Datasheet Fix Hot -
Since an official datasheet is hard to find, technical communities rely on these verified parameters: 32-bit / 384kHz SNR (Signal-to-Noise Ratio): >128dB DNR (Dynamic Range): >120dB THD+N: 0.0003% (-95dB) Output Power: 65mW (dual channel) Amplifier Class: Class G Why it Gets "Hot" (Common Causes)
Not every hot CX31993 is broken. The datasheet allows for junction temperatures up to 125°C. If your device meets the following, the heat is normal:
The CX31993 is not inherently bright. It is a transparent, high-performance DAC crippled by the lack of output filtering in cheap dongles. By applying a , you convert a “hot” dongle into a reference-grade source that rivals implementations costing 10x more. This fix is directly defensible from the chip’s own electrical specifications—and your ears will thank you.
If your chip is hot despite doing everything right electrically, you need to implement a . This is where the "modding" community shines. cx31993 datasheet fix hot
has established itself as one of the most popular budget USB-C to 3.5mm DAC chips in the audiophile community. Found inside widely praised dongles like the JCALLY JM6 and various "CX-Pro" models, it offers impressive performance metrics including , a 117dB to 128dB Signal-to-Noise Ratio (SNR) , and a highly competitive output voltage.
Users often report these chips getting warm during use. If yours is excessively "hot," try these common fixes:
You searched for "cx31993 datasheet fix hot" because you want action. Here is the definitive fix guide, from easiest to most advanced. Since an official datasheet is hard to find,
First, identify whether the primary source of heat is the CX31993 chip itself or a secondary amplifier IC.
dongle is operating at uncomfortable temperatures, apply the following fixes to reduce thermal output and improve longevity. 1. Optimize Software Settings (UAPP Fixes)
This article serves as both a deep-dive into the missing CX31993 datasheet (which Conexant no longer publicly provides) and a hands-on guide to fixing the thermal runaway. It is a transparent, high-performance DAC crippled by
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.
: While many standard CX31993 implementations run cool, units paired with a MAX97220 op-amp for higher power output (up to 125mW) are more prone to heating up.
