Product Introduction
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.
Features
- Integration Lowers System Cost, Simplifies Design Efforts, and Reduces Design Cycle Time
- Simple Conversion of Platinum RTD Resistance to Digital Value Handles 100Ω to 1kΩ (at 0°C) Platinum RTDs (PT100 to PT1000)
- Compatible with 2-, 3-, and 4-Wire Sensor Connections
- SPI-Compatible Interface
- 20-Pin TQFN and SSOP Packages
- High Accuracy Facilitates Meeting Error Budgets
- 15-Bit ADC Resolution; Nominal Temperature Resolution 0.03125°C (Varies Due to RTD Nonlinearity)
