Cx31993 Datasheet Fix Hot //free\\ Site

However, a persistent complaint echoes across audio forums and Reddit threads: Some users report thermal shutdowns, distorted audio after 30 minutes of use, or even intermittent disconnection. Manufacturers often shrug, claiming "warm operation is normal."

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: cx31993 datasheet fix hot

The CX31993 integrates a 32-bit, 384kHz DAC with a charge pump. The block diagram in the datasheet shows a direct path from the DAC to the headphone amplifier (HP AMP) output. There is no dedicated external analog LPF. This means ultrasonic noise (from delta-sigma modulation) folds into the audible band as intermodulation distortion, manifesting as perceived brightness. If your device meets the following, the heat

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)
