MAX31856MUD+T

Sensor And Detector Interfaces Overview

The MAX31856MUD+T is a precision thermocouple-to-digital converter featuring a 19-bit ADC and internal cold-junction compensation. It digitizes signals from K, J, N, R, S, T, E, and B thermocouples into Celsius with ±0.15% full-scale accuracy. The device provides 0.0078125°C resolution, supports temperatures up to +1800°C, and includes ±45V overvoltage protection. Operating on a single 3.3V supply (3.0V to 3.6V), it consumes 1.2mA during active conversion and 10µA in standby. It utilizes a standard SPI interface and is housed in a 14-pin TSSOP package.

Sensor And Detector Interfaces Feature Summary

• Includes automatic linearization correction for eight thermocouple types using an internal lookup table
• Provides integrated input protection against overvoltage conditions up to ±45V
• Features built-in fault detection for open circuits, over-temperature, and under-temperature events
• Incorporates 50Hz/60Hz noise rejection filtering to improve system performance

Sensor And Detector Interfaces Applications

• Temperature Controllers
• Industrial Ovens, Furnaces, and Environmental Chambers
• Industrial Equipment

Sensor And Detector Interfaces Procurement Notes

Verify the suffix 'T' indicates tape-and-reel packaging rather than tube. Confirm the component meets RoHS standards as indicated by the '+' designation. Ensure the specific lot date code aligns with project requirements before finalizing orders.

Sensor And Detector Interfaces Selection Notes

Select this model when high accuracy and wide temperature ranges are required. It eliminates external linearization components. Verify that the host microcontroller supports the necessary SPI clock speeds and data formats for reliable communication.

Sensor And Detector Interfaces Part Context

This part belongs to the MAX31856 family of precision thermocouple interfaces. It serves as a direct upgrade to older converters by offering higher resolution and broader thermocouple type support. The MUD+ variant specifically denotes the 14-pin TSSOP surface-mount package configuration.

Sensor And Detector Interfaces Replacement Considerations

The MAX31855 offers similar functionality but lacks support for Type B and E thermocouples. The MAX31856KFTG+ is the same functional device packaged in a 14-pin WDFW format instead of TSSOP.
