The MAX31865 is an easy-to-use thermistor to digital output converter optimized for platinum resistance temperature detectors (RTD).
The external resistor sets the RTD sensitivity, and the high-precision Δ- ΣADC converts the RTD resistor and the reference resistor to digital output. The MAX31865 input has an overvoltage protection of up to ± 45V, providing configurable RTD and cable open, short circuit condition detection.
