I am using STM32-NUCLEO L053R8 and I want to use 8 RTDs (Temperature sensors) to Analog pins of this microcontroller board. Is it possible I can use all ADCs simultaneously?

[SAHME.2]

This micro-controller has 16 Analog channels and I have read somewhere that all of these analog channels are sharing the same ADC. I want to connect 8 RTDs to the analog channels and I want this micro-controller to do conversion simultaneously. Is it possible ?
