Part Number: ADS1118 hii i came across your ADS1118 witch has a cold junction compensation built in feature build in . i have an application where i want to measure temperatures below 150C for Cryogenic temp range. and i wanted to know if there an application note that deals with Cryogenic temperatures measurements using the ADS1118 because in Cryogenic temp range the k TYPE thermocouple graph of the EMF (seeback effict ) is not constant and changes rapidly due the temperature change and i wanted to know how the ADS1118 outputs it values with SPI interface . where i can see a table that represents the temperature values in the spec?, and what is the accuracy of the temperature in the Cryogenic range ?
