The temperature measurement system based on AD7793 is based on the recommended document of ADI CN0206_cn.

PT100 is used as cold junction compensation, and 4-layer PCB cross-average temperature wiring.

SPI interface, support SPI daisy chain multi-channel applications.

The maximum thermal potential at 32 times gain is 36.5 mV, which corresponds to a K thermocouple index table of 850 degrees Celsius.

Provides an analog SPI reference program (STM32F10X)
