ADXL001 bode diagram

Hi,

I was wondering if I could get accurate phase delay for the accelerometers ADXL001.

I am doing experiments at 800Hz for which phase is crucial. Based on the Figure 1 of the ADXL001 datasheet (Sensor Frequency Response) and assuming that the response provided in dB is equal to 10log_10 (a_output/a_input) and that it is a second order system, I have estimated that the delay at that frequency is around 0.01rad. I would like to be able to correct for this deviation for which I would need, either the phase frequency response or accurate data of the gain frequency response to obtain the constants of the system.

Is there any place where I could find this information?

Thank you,

Regards,

Jmgl
