Product details

What this thermocouple converter does on your board

The Analog Devices MAX31850TATB+ is a thermocouple to digital converter that accepts multiple thermocouple types and outputs a digital signal. 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.

Frequently asked questions

Is MAX31850TATB+ compatible with T-type thermocouple?

Yes, the MAX31850TATB+ accepts multiple thermocouple types, including T-type. The part handles the linearization and cold-junction compensation for the thermocouple type selected.

Can I use MAX31850TATB+ for K-type thermocouple?

Yes, the input type is listed as Thermocouple (Multiple), which includes K-type. The device's internal firmware handles the conversion for the connected thermocouple alloy.

What is the closest pin-compatible alternative to MAX31850TATB+ in this component family?

The MAX31850 family includes variants for specific thermocouple types (e.g., MAX31850K for K-type only). 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.
