Analog scaling

I have analog Sensor output @ 9v . i wanna connect it to arduino input side. but pins are rated for 5v .

how can i convert it to 5v ttl level from 9v without losing precsion.
using voltage devider we can achieve above, but we loose precision ,
Is any other methods of doing it.

For sake of knowledge:
if input of analog input MCU are rated 3.3v and if i wanna give 5v Sensor output to analog input .how to read the exact analog output from Sensor

ttl level is 0volts or 5 volts, is your sensor 0-9v linear?

You could use an opamp to reduce the range without losing precision .

yes linear

using voltage devider we can achieve above, but we loose precision ,

Can you explain that, please?

What is the actual range of values you want to measure?

What resolution do you need?

Two 5K ohm resistors wired in series, one end wires to sensors 0-9vdc analog output pin, other end wires to ground, ground wires to both arduino ground pin and sensor ground pin, junction of two resistors wires to arduino analog input pin. Results are 0-9vdc from sensor is divided down to 0-4.5vdc suited to be read with analogRead() statements on arduino.
