MAX31865 Platinum Resistance Temperature Detector Module PT100 PT1000 RTD Sensor

The MAX31865 is an easy-to-use resistance-to-digital converter optimized for platinum resistance temperature detectors (RTDs). An external resistor sets the sensitivity for the RTD being used and a precision delta-sigma ADC converts the ratio of the RTD resistance to the reference resistance into digital form. The MAX31865’s inputs are protected against overvoltage faults as large as Q45V. Programmable detection of RTD and cable open and short conditions is included.
