当PSOC变热时，ADC14的读数突然下降很多并保持下降

嗨，大家好，
我遇到了ADC14的问题。
当PSoC的暖和，ADC14阅读突然下降明显，停留下来直到芯片冷却下来。我有一个电阻与输入简单的设计，不应该发生的。电压应稳定在5.00伏。
我可以通过加热PSoC的热空气和冷却下来，再次证明了好几次。
我说的开始温度20℃（常温）和最高温度50摄氏度（不要太烫）。跳动发生在摄氏40度左右。
直到现在我也不排除我有板的另一个设计问题，但我认为这可能与ADC的设置问题。
请你让我知道我会遇到什么问题？
最好的问候，

  Hi all,
    I am stuck with a problem with the ADC14.
    When the PSOC gets wARM, the reading of the ADC14 suddenly drops down a significant number and stays down until the chip has cooled down again. I have a simple PT1000 with a resistor attached to the input, nothing should happen there. The voltage should be stable at 5.00V.
    I could prove this several times by heating the PSOC with hot air and cooling it down again.
    I am talking about a start temperature of 20 degrees centigrade (normal room temperature) and a top temperature of 50 degrees centigrade (not too hot). The jump happens at around 40 degrees centigrade.
    Until now I can not exclude that there is another design problem on my board, but I think this may be a problem with the ADC or its settings.
    Could you please let me know what problem I might have run into?
    Best regards,
