MAX31865 Resistance Temperature Detector (RTD) to Digital Converter

The MAX31865 from Maxim Integrated is a resistance-to-digital converter optimized for platinum resistance temperature detectors (RTDs). This device 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.

Features

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)

Note

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