Measuring RTD sensors with Delta-Sigma ADS1220 family

ADS1220 Delta-Sigma family uses the ratiometric approach for measuring RTD sensors with the built-in current excitation source. Offset and gain calibration are required before the resistance measurement is converted into a temperature reading by the application MCU.
