Hi,
I am using an ads1271 and I noticed a nonlinear temperature response. When I connect the two differential input to the Vref and change the temperature from 30-80 deg.
This is the record of the temp and digital data
Red-ads1271 temperature
Perpol-ads1271digital output
Green- 60 samples averaging
You can see that in about 75 degree the grape starting to decline and at 80 deg going back up again.
This is a major problem for my system is there any solution?
