MAX31865 RTD-to-Digital Converter

General Description:

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 Q45V.
Programmable detection of RTD and cable open and short conditions is included.

Applications:

- Industrial Equipment
- Medical Equipment
- Instrumentation

Benefits and Features:

● Integration Lowers System Cost, Simplifies Design Efforts, and Reduces Design Cycle Time
