Hi,

This audio codec should be able to work from -40°C to 85°C. Do you have any other component or system in your circuit that could be affecting the codec behavior? Have you verified the power supplies level at this temperature? Could you provide any schematic to have a better approach to this issue?

Thank you.

Best regards,
