It is built for direct interface with a microcontroller, handling the cold-junction compensation and linearization internally. The 900 µA supply current keeps the thermal load on the measurement junction low, which matters when you are trying to resolve tenths of a degree in a temperature-controlled loop. ## Lifecycle and sourcing reality No end-of-life notice has been issued, and the part is ROHS3 compliant. For a BOM line that needs a thermocouple front-end with a digital output, this is a current-production choice — no last-time-buy risk, no need to qualify a replacement for an existing design.","metaTitle":"MAX31850TATB+ Thermocouple to Digital Converter","metaDescription":"MAX31850TATB+ is a thermocouple to digital converter from Analog Devices.

The MAX31850TATB+ is the variant that handles multiple types. A direct pin-compatible replacement would be another MAX31850 variant with the same package code; verify the thermocouple type support against your probe before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX31850TATB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX31850TATB when reusing this data.
