Is there a specification for change in zero rate level vs time?

If I measure the zero rate level for a few seconds, I can get an average measurement and use it to cancel out drift. However, the zero rate level changes over time. I want to choose a gyro with the smallest drift. How is change in zero rate level specified in the data sheet? I can't find it.

Thanks,

Osman

Hello Osman,

What is the gyroscope that you are referencing?

For L3GD20, the attached datasheet contains on page 9, table 3 a section showing the zero-rate behavior depending on the FS.

Please let me know if this was the information that you were looking for.

Thank you,

Thiago Reis
