S32K344 Temperature Sensor

The IC temperature value was obtained from the ADC0-19 channel and calculated using the code shown in the figure below. However, the temperature value fluctuates severely. What is the reason for this? How to solve it?

Hi@liyongfeng

We have provided you with API functions to calculate temperature sensor conversions

please test the function below:

Adc_Sar_Ip_TempSenseCalculateTemp();

I used this API, but there was no improvement. The temperature value is still jumping

According to parameter TS-ACC2, Is it allowed for temperature fluctuations to occur within the range of ±10 ℃?

Hi@liyongfeng

Could you please provided your project and i will help you to check it agian.

The temperature sensor will have errors, but there will not be such a large fluctuation

Because this is the project code, we cannot provide it to you. Can you provide me with a good demo of S32K344?
