ADxL345 and ADuM2401

Hi,

In my application I am using ADXL345 Accelerometer.
The Microprocessor used is C8051F120.

At beginning of the project I used the ADXL345 directly connected to the micro (without isolation) and the accelerometer work perfectly.

I have added some sensitive analog circuits that required isolation from the Micro ground and due to some compulsions I tied the Accelerometer to the Analog ground and used the ADuM2401 as isolator between the Micro to the Accelerometer (see attached drawing), at this stage the accelerometer stop to function even though it receives all necessary control signal as before adding the isolator.

I need your urgent help, please advise.
