LIS3DH ODR vs System Bandwidth Clarification

Question asked by Louie Francis Ouano on May 22, 2018

On Section 3.2.1 of the datasheet(DocID17530 Rev 2), there is a column in Table 10 called "BW[Hz]", this is the "system bandwidth". The datasheet does not discuss more details on what the "system bandwidth" means but I'm assuming this indicates the real output data rate. Is this correct?

 

So going back to Table 10, if I am configuring LIS3DH into High-resolution mode and an ODR of 400Hz the BW is ODR/9. If my above assumption is correct, this would mean that the real output rate is actually 44Hz(i.e.,400/9)?

 

Thanks.
