STM32L Discovery Board - OPAMP question

I have a question about the OPAMPs present in the ucontroller. 

According to STM32L1XX.H 3 OPAMPS are available that can be used by driving the inverting/non-inverting input and output to different pins of the board by some switches.

However it is not clear what switches connect to what pins on the board. Is there any picture that explains this?

Are the power supply of the OPAMPs V- = GND and V+ = 3V ?

Hi Marco,

You have to check the datasheet of the used MCU (Ex:

)
