I made a board with STM32L476RG chip to pick up a little signal with ADC module, but ended up with a severe distortion. Then I tested the board with sine signal of 20mVpp, 300mVbias. The signal is generated by a signal generator. The result can be s...

Hi, I'm trying on stop mode lately, and also encountered with this problem.I searched a lot and finally found a error description in page 12 of document "stm32wb55xxstm32wb35cx-device-errata" which is related to this error.Incorrect exit from Stop mo...

I updated my observation above and I think I have found the reason.

Thank you for the suggestions, I will check the pins. And I will try different signal source. I will update my results in the discription of the question.

Actually, the resolution of the 2 boards are all 12-bit, so it is really strange.I tried both 50Ω and Hiz impedance of the input signal, but turned out that this odd behavior didn't change.

While using STM32L476 ADC to monitor a signal, the data showed a severe distortion. Has anyone comed up with such a problem?
