Shift 10-15v to 0-5v
You could shift the 10-15V to something like 0.5 to 4.5V with a single 5V supply and you would not lose out much on resolution. You can use pretty much any op-amp that meets your precision requirements and has a rail-to-rail output.

One advantage of using a single 5V supply and giving up that 20% resolution is that you don't need to worry about clamping the op-amp output at the MCU rails.
