The MAX31855TASA+T is a thermocouple-to-digital converter designed by Analog Devices / Maxim Integrated. This integrated circuit performs cold-junction compensation and digitizes signals from various thermocouple types, including K, J, N, T, S, R, and E. It provides a signed 14-bit output in a read-only SPI-compatible format, achieving a resolution of 0.25°C.
Key features include integrated cold-junction compensation, detection of thermocouple shorts to GND or VCC, and open thermocouple detection. The device operates within a supply voltage range of 3.0V to 3.6V and has an operating temperature range of -40°C to +125°C. Its accuracy for K-type thermocouples is ±2°C for temperatures between -200°C and +700°C.
This component is housed in an 8-SOIC surface-mount package, making it suitable for various industrial, appliance, and HVAC applications. The simple SPI interface allows for easy integration with most microcontrollers, reducing design time and system cost.
