I don't find any information about the input impedance in the datasheet. Could
you provide me any?


We do not have the data that you are looking for. Based on what we know about
the design, differential resistance is roughly 6 MΩ, common mode resistance is
around 1 GΩ and input capacitance is <7pF.
