Hi I am looking for help to find out which STM32 MCU have at least 3 parallel and independent ADC’s available in them? Your help is highly appreciated.

How hard can it be to just look at some of the part families? What OTHER requirements do you have that might limit your choices?

F1 3x ADC

F2, F4 3x

F3 4x

L4 3x

There's a field in the table here indication the number of ADC in a specific package/part choice
