Does the AD8495 thermocouple amplifier allow for grounded thermocouple probes?

Question

I recently purchased a MAX31856 thermocouple-to-digital chip for a project. However, I discovered that the chip does not support grounded thermocouples. I am looking for an alternative and the AD8495 appears to be the only similar option. However, I cannot tell from the datasheet whether it supports grounded thermocouple probes. How can I tell?

Answer 1

You can use it.

In the 1st paragraph at pg 12 it tells how the IC deals with the problems coming from single-ended (i.e. grounded one end) TC usage.

The last sentence of that paragraph is the answer.

The excellent common-mode rejection of the AD849x prevents variations in ground potential and other common-mode noise from affecting the measurement.
