TLV320AIC3256: TLV320AIC326 Temperature change causing MIC_detect issue.

Part Number: TLV320AIC3256

Hi Team,

My customer is running into a problem where MIC_Detect fluctuates without unplugging the MIC when the ambient temperature changes from 25C to -40C and -40C to 25C( they said the problem is easily reproduced when they open the door of the chamber when it's -40C)

We can see from the waveform the TIP1 is always low and the MIC_Detect jumps.

Have we seen this issue before?
