Need allan variance plot for LSM6DS33TR accelerometer and gyroscope

[AKuma.12]

Hi Team,

Allan variance plot is missing in the datasheet. I need that to estimate White noise, rate random walk and bias stability.

I have came up with this document https://www.st.com/content/ccc/resource/technical/document/design_tip/group0/bf/92/6b/31/e7/c1/4d/c8/DM00311184/files/DM00311184.pdf/jcr:content/translations/en.DM00311184.pdf

But, this document seems to have gyroscope allan variance plot only.

Please share me the allan variance plot for LSM6DS33TR accelerometer and gyroscope.

Thanks,

Ajith Kumar

Can you please provide me the contact mail ID of the tech support?

I actually couldn't find one from the contacts page.

Hi Ajith, I can share you a few average parameters for the Gyro and XL LSM6DS33TR Allan Variance (value for x, y, z or pitch, roll, yaw axis): Axl VRW (velocity random walk) = (9.18, 10.5, 19.5) mg*s/sqrt(h); Axl BI (Bias stability) = (215, 222, 269) mg*s/h; Gyro ARW (angular random walk) = (0.53, 0.62, 0.52) deg/sqrt(h); Axl BI (Bias stability) = (20.3, 20.9, 15.5) deg/sqrt(h). Hope could be enough. Regards
