Use STM32H743II with an external ldo for vcore @ 400MHz

We would use a STM32H743II with an external ldo for vcore. In the datasheet are tables (page 114, table 31) with regulator on but no tables with regulator off.In the datasheet at page 114 is a table (table 31) for maximum current vs. junction tempera...

Resolved! Using an ADC how can I make the value of Vref- depend on the value of another input on a STM32H742 chip?

I need to implement an ADC to measure phase voltages, so I want to set the N phase as Vref- and get the values of other 3 phases (comparing with N phase) on the output of the ADC. I am using single-ended mode.Is it possible to do this? How can I do i...
