Product Overview

The MAX31855JASA+ is a cold junction compensated thermocouple to digital converter with built-in 14bit analogue to digital converter in 8 pin NSOIC package. The device contains cold junction compensation sensing and correction, digital controller, SPI compatible interface and associated control logic. It is designed to work in conjunction with an external microcontroller (μC) in thermostatic, process control or monitoring applications. The MAX31855J performs cold junction compensation and digitizes the signal from J type thermocouple with measuring temperature range of -40°C to +750°C. The Thermocouple temperature gain and offset error (57.953μV/°C nominal sensitivity) is ±2°C at T (thermocouple) = -210°C to +750°C, TA = -20°C to +85°C. The data outputs in a signed 14bit, SPI compatible read only format.
