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 ±45V. Programmable detection of RTD and cable open and short conditions is included.

Applications include; Industrial equipment, medical equipment & instrumentation.

Features & Benefits:


• Simple Conversion of Platinum RTD Resistance to Digital Value
• High Accuracy
• Over All Operating Conditions
• Integrated Fault Detection - ±45V Input Protection, Fault Detection (Open RTD Element, RTD Shorted to Out-of-Range Voltage, or Short Across RTD Element)
• Handles 100Ω to 1kΩ (at 0°C) Platinum RTDs (PT100 to PT1000)
• SPI-Compatible interface
• 15-Bit ADC resolution
• Fully Differential VREF Inputs
