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.
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.
