We are using an STM32G491 with TDM audio output active on SAI. When activating the 4 MHz bit-clock on SAI1_SCK_A, Vref and temperature measurement become very noisy, while externally connected ADC inputs are not affected.See attached graph for differ...

We are using the ADC on an STM32G4xx for a safety project. The safety manual requires us to read VSS or VDD for ADC diagnostics. STM32G4 has ADC channel 0 internally connected to VSSA, so we are trying to use HAL_ADC_ConfigChannel() to configure ADC_...
