Hello,

I am using a the analog accelerometer ADXL335 on a Grove board. The data-sheet (p.11, right column) says that the resolution depends on the Bandwidth (which in turn depends on Cx, Cy, Cz).

Can someone let me know the equation/relation linking the Resolution to Bandwidth.?

Thanks,

Arun

• I didn't write this datasheet, but I would interpret this as equating resolution to the noise in the measurement, which is proportional to the square root of bandwidth.

Total Noise = Noise Density x sqrt(Noise Bandwidth)

For example, when the noise bandwidth is 16Hz, the total noise would be

Total Noise =150ug/sqrt(16) = 600ug = 0.6mg

I hope that helps!
