opamp front end for 5v analog sensors!

I have an idea to adapt 5v analog sensors to the 1.8v adc that will not impact resolution. We can use an op amp to preprocess the analog signal.
I will work on and test the circuit and post later. I should get to this after I finish prototyping my motor controller. When I have that done I will need to convert my current sense voltage output.

If the ADC input impedance is high enough, a simple resistor voltage
divider should work.
