MAX31865 Resistance Temperature Detector (RTD) to Digital Converter

The MAX31865 series from Maxim Integrated is a resistance-to-digital converter optimized for platinum resistance temperature detectors (RTDs). This device also utilises a precision delta-sigma analogue-to-digital converter (ADC) to convert the ratio of the RTD resistance versus the reference resistance into digital form. This reference resistance is set through the application of an external resistor.

Applications can include; Industrial equipment, medical equipment & instrumentation.

Features and Benefits:

• Simple Conversion of Platinum RTD Resistance to Digital Value
• Compatible with 100Ω to 1kΩ (at 0°C) Platinum RTDs (PT100 to PT1000)
• Compatible with 2-, 3-, and 4-Wire Sensor Connections
• SPI-Compatible Interface
• 15-Bit ADC Resolution Nominal Temperature Resolution 0.03125°C (Varies Due to RTD Nonlinearity)
• Total Accuracy Over All Operating Conditions: 0.5°C (0.05% of Full Scale) max
• Fully Differential VREF Inputs
• 21ms (max) Conversion Time
• ±50V Input Protection
• Fault Detection (Open RTD Element, RTD Shorted to Out-of-Range Voltage, or Short Across RTD Element)


Please note that any defect or non – conformance of this product must be discovered and reported to RS within 20 days of purchase.
