MAX31850TATB+

Sensor And Detector Interfaces Overview

The MAX31850TATB+ is a cold-junction compensated, 1-Wire thermocouple-to-digital converter optimized for T-type thermocouples. It digitizes signals with 14-bit resolution (0.25°C) and supports readings from -270°C to +400°C. The device features integrated cold-junction compensation, fault detection for shorts and open circuits, and parasite power capability. Operating voltage ranges from 3.0V to 3.7V, with an active supply current of up to 1750µA at 3.7V. It operates within a temperature range of -40°C to +125°C in a 10-TDFN (3mm x 4mm) package.

Sensor And Detector Interfaces Feature Summary

• Integrated cold-junction compensation and 14-bit analog-to-digital conversion
• Single-wire 1-Wire interface supporting parasite power mode
• Built-in fault detection for thermocouple shorts and open circuits

Sensor And Detector Interfaces Applications

• Industrial temperature monitoring systems
• HVAC equipment
• Medical devices requiring precise thermal sensing

Sensor And Detector Interfaces Procurement Notes

Verify the specific suffix 'T' confirms T-type thermocouple compatibility. Confirm the 'ATB+' designation indicates the TDFN-EP package and lead-free status. Ensure the source document matches the official Maxim Integrated datasheet for the MAX31850/MAX31851 family to validate electrical parameters.

Sensor And Detector Interfaces Selection Notes

Select this component when a single-wire interface is required to minimize wiring complexity. Choose the T-type variant specifically for applications involving temperatures below 400°C where its sensitivity profile is optimal. Consider parasite power requirements if external VDD routing is restricted.

Sensor And Detector Interfaces Part Context

This part belongs to the MAX31850/MAX31851 family of thermocouple-to-digital converters. The MAX31850 series supports K, J, N, T, and E types, while the MAX31851 supports S and R types. The MAX31850TATB+ is the specific iteration configured for T-type thermocouples.

Sensor And Detector Interfaces Replacement Considerations

MAX31850KATB+ for K-type thermocouples. MAX31850JATB+ for J-type thermocouples. MAX31850EATB+ for E-type thermocouples. MAX31850NATB+ for N-type thermocouples. All share identical pinouts and interfaces but differ in internal calibration tables.
