MAX31850TATB+T

Sensor And Detector Interfaces Overview

The MAX31850TATB+T is a cold-junction compensated, 1-Wire thermocouple-to-digital converter optimized for K-type thermocouples. It digitizes signals from K-, J-, N-, T-, S-, R-, or E-type thermocouples with a 14-bit resolution of 0.25°C. The device supports temperature readings from -270°C to +1768°C and provides thermocouple accuracy of ±2°C within the -200°C to +700°C range. Operating on a supply voltage of 3.0V to 3.7V, it features integrated fault detection for open circuits and shorts. Communication occurs via a single-wire interface that allows parasite power operation.

Sensor And Detector Interfaces Feature Summary

• Integrated cold-junction compensation eliminates external sensing components
• Single-wire 1-Wire interface enables simplified multi-drop sensor networks
• Built-in fault detection identifies open thermocouples and shorts to ground or supply
• Unique 64-bit ROM code facilitates individual addressing on shared buses

Sensor And Detector Interfaces Applications

• Industrial process control systems
• HVAC monitoring equipment
• Medical diagnostic devices
• Home appliances with temperature regulation

Sensor And Detector Interfaces Procurement Notes

Verify the specific suffix 'K' confirms K-type thermocouple compatibility. Confirm the 'TA' designation indicates the extended industrial temperature range. Ensure the '+T' suffix matches the required tape-and-reel packaging format for automated assembly processes.

Sensor And Detector Interfaces Selection Notes

Select this component when a single-wire communication protocol is required to minimize wiring complexity. Choose this part over SPI-based alternatives if parasite power capability is necessary for remote sensor placement. Verify that the K-type thermocouple sensitivity aligns with the application's specific temperature measurement requirements.

Sensor And Detector Interfaces Part Context

This device belongs to the MAX31850/MAX31851 family of converters. The MAX31850 variant specifically supports K, J, N, T, and E types, while the MAX31851 supports S and R types. Both share identical interfaces and compensation architectures but differ in internal calibration tables.

Sensor And Detector Interfaces Replacement Considerations

MAX31850JATB+T: Supports J-type thermocouples instead of K-type. MAX31850NATB+T: Supports N-type thermocouples instead of K-type. MAX31850TATB+T: Supports T-type thermocouples instead of K-type.
