Hi,everyone.I'm use NUCLEO-L496ZG platform.ADC1 sample at a frequency of 5M,ADC3 sample at a frequency of 12.8K(PWM trigger).when only run ADC3,ADC3's waveform is normal.when ADC1 and ADC3 run at the same time,ADC3's waveform has a lot of interferenc...

thanks for you reply, ADC1 and ADC3 is not sample the same signal, what ever ADC1 sample Any frequency even if ADC1 is grounding ,only ADC1 run, ADC3 has interference. Pulse signal generator output voltage into STM32 analog IO.(single-ended input)

Thank you for your response. The picture is Time-domain waveform. Y axis value read from ADC3 regular data register (ADC_DR), X axis is counts.
