ADXL345 frequency response

Hello!

 

I have a question on the frequency response of the ADXL345 at very low frequencies.  The data sheet clearly shows that it is possible to reach a 0.1Hz

However, this app note (AN-688) shows phase response falling off at 10Hz.

I realize that this is an older accelerometer, but I don't see any such chart for the ADXL345 in the data sheet.  Is this phase response similar to the ADXL345?  Do you have any data on that you can share?

 

Thanks,

Ryan
