I was looking at the: "Analog Output K-Type Thermocouple Amplifier - AD8495 Breakout" and was wondering if I supplied the chip with more power if I would get a wider output temperature range? I am using a simple k-type thermocouple off of amazon and using it to measure the exhaust gas temperature of my car with an arduino uno micro controller.
"Temp range with 5V power: -250°C to +750°C output (0 to 5VDC)"
So if I supplied it with more than 10volts would I be able to measure over 1000degrees Celsius and read it with my arduino uno?
Thanks!

Re: AD8495 Question
Good question. I couldn't quite derive a definitive answer from the datasheet, although it appears that you get a wider range with a higher supply voltage.
However, you're limited by the Uno. That definitely has a maximum input analog voltage of 5V. So, you'd have to divide down the output voltage of the thermocouple amp to avoid exceeding that limit.

Re: AD8495 Question
Thanks for the reply Rick. I think I will just go with one of the chips that's utilizes a max. Thanks for the help though!
