MAX31850EATB+

Sensor And Detector Interfaces Overview

The MAX31850EATB+ is a cold-junction compensated, 1-Wire thermocouple-to-digital converter optimized for E-type thermocouples. It digitizes signals from K-, J-, N-, T-, S-, R-, or E-type thermocouples with 14-bit resolution and 0.25°C precision. The device supports supply voltages between 3.0V and 3.7V and operates within a temperature range of -40°C to +125°C. It features integrated fault detection for open circuits and shorts, parasite power capability, and unique 64-bit addressing.

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 diagnostics for detecting open thermocouples and shorts to ground or VDD

Sensor And Detector Interfaces Applications

• Industrial process monitoring
• HVAC systems
• Medical equipment
• Appliance temperature sensing

Sensor And Detector Interfaces Procurement Notes

Verify the specific suffix 'EA' corresponds to the E-type thermocouple variant and the 'TB+' indicates the TDFN-EP package configuration. Confirm RoHS compliance status through official manufacturer documentation before procurement. Ensure the ordering code matches the exact pinout and thermal characteristics required for the target PCB layout.

Sensor And Detector Interfaces Selection Notes

Select this component when an E-type thermocouple interface is required alongside a 1-Wire digital bus. Consider the 14-bit resolution and integrated compensation for applications needing high accuracy without external signal conditioning. Evaluate the TDFN-EP package size against available board space and thermal dissipation requirements.

Sensor And Detector Interfaces Part Context

This part belongs to the MAX31850/MAX31851 family of thermocouple-to-digital converters. The MAX31850 series specifically supports K, J, N, T, and E types, while the MAX31851 supports S and R types. The MAX31850EATB+ represents the E-type specific version in the TDFN-EP package.

Sensor And Detector Interfaces Replacement Considerations

MAX31850KATB+ (K-type), MAX31850JATB+ (J-type), MAX31850NATB+ (N-type), MAX31850TATB+ (T-type). These parts share identical interfaces and functionality but are calibrated for different thermocouple types.
