Maxim MAX31855NASA+T

热电偶到数字转换器热电偶（多重）数字

Overview

The MAX31855NASA+ is a cold junction compensated thermocouple to digital converter in 8 pin NSOIC package. This is a "N" type sophisticated thermocouple to digital converter with a built-in 14bit analogue to digital converter (ADC) also contains cold junction compensation sensing and correction, a digital controller, an SPI compatible interface (read only) and associated control logic. The function of the thermocouple is to sense a difference in temperature between two ends of the thermocouple wires and it has a signal-conditioning hardware to convert the thermocouple's signal into a voltage compatible with the input channels of the ADC. The device is designed to work in conjunction with an external microcontroller (µC) in thermostatic, process-control or monitoring applications.
