Reading a 1.2V-8.8V Signal into a 5V Arduino Input
There will be resistors on some levels. If you like ICs, you can buy IC which contains multiple resistors:

Or you could use fixed-gain amplifier which has resistors + amplifier in one package. But this will be an overkill, as your output is already from amplifier, plus most fixed-gain amplifiers have gain > 1

Or you can use ADC which takes -10V..+10V range and returns I2C data such as MAX127/MAX128.

Or you could just connect amplifier directly to Arduino. Output will only exceed 5V if temperature is > 590C. What is the max temperature of the thing you are trying to measure?
