MAX31865 RTD-to-Digital Converters

Analog Devices Inc. MAX31865 RTD-to-Digital Converters are easy-to-use resistance-to-digital converters 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 ±50V. Programmable detection of RTD and cable open and short conditions is included.
