Can i interface two different analog inputs to single pin(which is having two different ADC channels assigned ) of multi mode ADC in the STM32f205ZCCTTR. Can i scan those two with help of multimode ADC of STM32.?

If can, please share the physical connection diagram (two Analog voltage sources to single pin micro controller ) and sample code for that.

If I understand the question correct ...

Not at the same time. You would have to re-initialize the other setup each time you want to read the other channel.

If you short on pins, consider an external analog multiplexer. Similar to the 4067 / 74HC4067 CMOS device: https://en.wikipedia.org/wiki/List_of_4000-series_integrated_circuits
