Hi Team,

Can I use 2 ADCs of same channel configured in same ADC PIN PA3 pin where ADC-1 is at 1KHz trigger timer in timer1 and ADC-2 at 2KHz trigger timer in timer3.

Hello,

It's feasible but becarefull if the two ADC's sample the same channel at the same time. You will face some conversion disturbance due to the internal capacity of each ADC that will be set in parallel at that time. So it's recommended to use dual interleaved mode.
