MAX31865ATP+ by Analog Devices

RTD-to-Digital Converter

Status: Active
Series: MAX31865
RoHS: Unknown
View Datasheet Manufacturer Site View Pricing & Stock

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.
