MAX31850JATB+T

Sensor And Detector Interfaces Overview

The MAX31850JATB+T is a cold-junction compensated, 1-Wire thermocouple-to-digital converter optimized for J-type thermocouples. It digitizes signals with a resolution of 0.25°C and supports readings from -270°C to +1200°C. The device operates on a supply voltage range of 3.0V to 3.7V and draws up to 900µA in active mode. It features integrated fault detection for open circuits and shorts, and communicates via a single-wire interface that supports parasite power.

Sensor And Detector Interfaces Feature Summary

• Integrated cold-junction compensation eliminates the need for external reference sensors
• Single-wire 1-Wire interface enables simplified multi-drop sensor networks
• Built-in fault detection identifies open thermocouples and shorts to ground or supply

Sensor And Detector Interfaces Applications

• Industrial process control systems
• HVAC temperature monitoring
• Medical equipment requiring precise thermal regulation

Sensor And Detector Interfaces Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing components. Confirm the 'J' designation matches the required J-type thermocouple application. Ensure the supplier provides original manufacturer documentation to validate authenticity and traceability.

Sensor And Detector Interfaces Selection Notes

Select this component specifically for J-type thermocouple applications due to its internal calibration. Consider the 1-Wire interface requirements for the host microcontroller. Evaluate whether parasite power is sufficient or if an external VDD supply is needed for high-temperature conversions.

Sensor And Detector Interfaces Part Context

This part belongs to the MAX31850/MAX31851 family of thermocouple converters. The MAX31850 variant supports K, J, N, T, and E types, while the MAX31851 supports S and R types. This specific model is the J-type version packaged in a 10-TDFN format.

Sensor And Detector Interfaces Replacement Considerations

MAX31850KATB+T (K-type), MAX31850NATB+T (N-type), MAX31850TATB+T (T-type). These share identical interfaces and pinouts but are calibrated for different thermocouple types.
