We had a product used TLV320AIC3268 for Audio application, and already made a PCB.
The application of product is automotive infotainment so the ambient temperatur would be up to 70 degree C.
At the product testing, TLV320AIC3268 didn't work correctly at the ambient temperature up to 70 degree C.
When the system works at room temperature, the function is right. It can record from MIC and playback.
When the ambient temperature is up to 70 degree C, it can't record from MIC. But, it can playback.
The operation temperature showed on datasheet is from -40 to 85.
Is TLV320AIC3268 suitable for this application? or we can adjust setting to fixed it.
