The MAX31865 RTD-to-Digital Converter module interfaces PT100/PT1000 platinum resistance temperature detectors (RTDs) with microcontrollers via SPI. A precision delta-sigma ADC converts the RTD-to-reference resistance ratio to digital form. Built-in fault detection for open and short-circuit RTD/cable conditions. Overvoltage protection up to 45V on inputs.
