Thread Summary

                The user inquired about estimating the minimum and maximum TEC current accuracy for a narrower temperature range (0 to 70°C) based on a datasheet showing a 10% accuracy over -40°C to +125°C. The support engineer confirmed that the accuracy should be tighter within the narrower range but did not provide specific values. The ADN8833 TEC Driver was mentioned in the context.

HI,




The datasheet has the following table for the TEC current accuracy under the test conditions between -40C to +125C and the min and max seem to be off a lot from the test current of 700mA.


What can we estimate the min and max for a narrower temperature range 0 to 70C?




Thanks


Ming
