    Hi. 
    
 
    As i detected in Adxrs623's  datasheet, Null voltage has around +_100mv Voltage instability.
    
 
    The problem is the Scale factor is around 12.5mV. So the Null voltage instability is a huge problem for me(100mv means 100mv/12.5mvperdeg/sec=8deg/sec)
    
 
    what is your suggestion for solve this problem?
    
 
    thanks.

      Thank you for your post! It's good to hear from you again. As we described in our other discussions, most people use an A/D converter into a processor, which will apply calibration coefficients to correct for these behaviors. Some of these behaviors are power supply dependent, some of them are temperature dependent and some of them or more related to time and mechanical stress. What level of absolute accuracy do you require for your application?
