MAX31855KASA+ Description

Short technical summary and product information.

The MAX31855KASA+ from Analog Devices is a thermocouple-to-digital converter designed for accurate temperature measurements. It performs cold-junction compensation and digitizes signals from various thermocouple types, including K, J, N, T, S, R, and E-type.

 

This device offers a 14-bit resolution, providing temperature readings with 0.25°C increments. It can measure temperatures as high as +1800°C and as low as -270°C. For K-type thermocouples, it exhibits an accuracy of ±2°C within the -200°C to +700°C range.

 

The MAX31855KASA+ features a simple SPI-compatible interface for easy integration with microcontrollers. It operates within a supply voltage range of 3.0V to 3.6V and has an operating temperature range of -40°C to +125°C. The converter also includes detection for thermocouple shorts to GND or VCC, and open thermocouples.

 

Packaged in an 8-SOIC format, this component is designed for surface mount applications. Its integration reduces design time and lowers system cost, making it suitable for industrial, appliance, and HVAC applications.
