Accelerometer Damping Factor ?

Hi

Could you tell me if there is a typical damping factor Analog accelerometers are designed for and particularly what it is for the ADXL325 and ADSXL326 please?

 

The resonant frequency is given as 5.5kHz in the data sheets and in my application it is configured with a filter bandwidth of 250Hz and I'm particularly interested in performance at the low frequency end <10Hz.

 

I've looked for this information through the various documents, references and forums but couldn't find it, other that one article recommending assuming it is critically damped, so I apologise if I've missed this somewhere.

 

Thanks

Nick
