What is the value of the input impedance of the OP-AMP inside the STM32U575?

[sini]

Dear ST,

I am trying to configure a voltage follower usin intenal op-amp for external voltage monitoring. And we are going to read that value through ADC.

Therefore, it is necessary to select the resistance value of the voltage divider.

So I want to know what is the value of the input impedance of the op-amp.

Best regards
