Cx31993 Datasheet Fix Hot

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:

| Missing Datasheet Section | Consequence | |---------------------------|-------------| | Thermal resistance (θJA) | Cannot calculate required PCB copper area for heat sinking | | Maximum junction temperature (Tj max) | No safe operating limit | | Output current vs. temperature derating | No guidance on volume/power limits | | Recommended thermal vias or pad layout | PCB designers omit heat dissipation structures | | Internal regulator power dissipation | No way to estimate heat from LDOs inside the chip | cx31993 datasheet fix hot

It is normal for high-performance portable DACs to generate heat because they draw significant power (often pulling Not every hot CX31993 is broken

Applying small VRM heatsinks and thermal pads to the internal PCBA has been shown to drop operating temperatures from to roughly temperature derating | No guidance on volume/power limits
