Can I use this opamp as a buffer for a given input range and supply voltage?
It should be fine for a non-precision application such as a windvane potentiometer. Your actual application circuit (please edit the question and add this information to the question) shows an input that goes from about 100mV to the excitation voltage minus 100mV. The amplifier you are looking at can even sink a bit of current at that minimum output voltage (typically as much as 2mA according to figure 6).

You could probably use a much cheaper single supply op-amp instead. You may find that a bipolar type is easier to protect, although with a CMOS type you can add a large value resistor to the input without unduly affecting accuracy (much higher than the 1K shown). The absolute maximum 15.5V supply voltage is a bit closer than one might like to 12V.
