Forum Post: ADS1118 Total error

Hi,

We are planning to interface 2 thermocouples to ADS1118. Both are of Type K thermocouple, whose output is Linear in the -40 to +1200degC range, and has a slope of 0.040706 mV/degC.Operating temperature range of Electronics is -40 to +125degC.  What is the Total temperature error (due to noise, offset, Gain error) that we can expect if these thermocouples are interfaced to ADS1118.
