Compiler/ADS1292: Handling Temperature coefficient with ADS1292

Part Number:ADS1292

Tool/software: TI C/C++ Compiler

Hello,

i am using ADS1292 for current measurement( 4mA input gives 0.4v and 20mA gives 2v) hardware is working fine. Now on temperature chamber testing we found that on higher temperature

its not giving accuracy (we need 0.05%), its giving 10 time more i.e. on temperature raise(30 degreeC-60 degreeC) results are deviating from 0.05 to 0.5%, which is not accepted for product CE certificate.

Kindly let me know is there any temperature coefficient that can be added/calculated for ADS1292, on temperature changes from 30 degreeC-60 degreeC.

Any generic formula available for ADS1292.

Thanks in advance,

Nitesh
