    Thread Summary
    
                The user inquired about the temperature coefficient (Tempco) stability of the 2.5k version of the AD5248 after wiper movement, noting the 10k version stabilizes below 20ppm after code 10. The support engineer provided the typical temperature drift values for all versions: 35 ppm/°C for rheostat mode and 15 ppm/°C for potentiometer mode.

    Hello!
    

    

    Data sheet of AD5248 provides performance characteristics only for 10k version. 
    

    I would like to know temperature coefficient of 2.5k version (10k version : AD5248 datasheet, Fig.17 on page 9. Rheostat Mode Tempco ΔRWB/ΔT vs. Code)
    

    Can I get some relation between 2.5k version and 10k version? exactly, how much code dose Tempco of 2.5k version get stable after the wiper goes?(10k version seems to be below 20ppm after code = 10)
    

    

    thank you!
