ADS124S08: What situation or application will the Vbias of ADS124S08 be used for?
The VBIAS can be used is cases where you have a floating sensor voltage. VBIAS is used to bias the sensor within the input range of the ADC. The most common type or sensor application that would use VBIAS is a thermocouple. Although other types of sensors can be used the VBIAS has limited sinking/sourcing capability.
Similarly the burn-out current sources (BOCS) are used for detecting opens/shorts in the sensor path and most commonly used with thermocouples.
I would suggest taking a look at A Basic Guide to Thermocouple Measurements:
