Answer:
"In most cases, a thermocouple is not referenced to or biased toward any system power supply voltage. Therefore, the VBIAS function must be used when connecting a thermocouple to the AD4110-1. Enabling VBIAS effectively grounds the AIN(−) side of the thermocouple to the ground of the AD4110-1 power supply. For more information, see the section."
