MAX31865 RTD-to-Digital Converter General Description 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 Q50V.
Programmable detection of RTD and cable open and short conditions is included.
Features S Simple Conversion of Platinum RTD Resistance to Digital Value S Handles 100Ω to 1kΩ (at 0°C) Platinum RTDs (PT100 to PT1000) S Compatible with 2-, 3-, and 4-wi...
