MAX31855KASA+T Description

Short technical summary and product information.

The MAX31855KASA+T from Analog Devices is a thermocouple-to-digital converter designed for industrial, appliance, and HVAC applications. It performs cold-junction compensation and digitizes signals from K-, J-, N-, T-, S-, R-, or E-type thermocouples.

 

This device features a 14-bit resolution, providing temperature readings with 0.25°C increments. It supports a wide temperature range, allowing readings as high as +1800°C and as low as -270°C. For K-type thermocouples, it exhibits an accuracy of ±2°C for temperatures between -200°C and +700°C.

 

The MAX31855KASA+T interfaces with most microcontrollers via a simple SPI-compatible, read-only format. It also includes features to detect thermocouple shorts to GND or VCC, as well as open thermocouples.

 

Packaged in an 8-SOIC (0.154", 3.90mm Width) surface-mount package, this converter operates within an ambient temperature range of -40°C to +125°C. Its typical operating current is 900 µA.
