Do you have any models or data that illustrates the ADXL001 frequency response?



Yes, please see the attached m-script file, ADXL001Response.m, which simulates the ADXL001 response using Matlab. Here are the Matlab workspace commands for using this file:

>> R = 100;

>> C = 47000/(10^12);

>> ADXL001Response(R, C)

Note  that the "R" value is added to the ADXL001's effective source impedance  for small signal analysis, 100 ohms, inside of the ADXL001Response.m  file. This number can be increased to add any discrete filter resistance.  In the curve below, blue line represents the accelerometer core,  the red line represents the external filter and the green line is the  composite response.  Click on the following link to see the simulation plot response from this model.



Also, please see the attached file for a set of test data.
