Digital Accelerometer antialiasing filter

Hello, I have a question about MEMS accelerometers with digital interface. From the block diagram (es: ADXL312) seems that no antialising filter is put between the sensing cell and the ADC.  A "sense electronics" block is present in the diagram but there are no indication about the real content of it.  I would like to know if a fixed filter, set at the maximum bandwidth, is present or not. (specifically in the ADXL312 or for other member of digital mems).

Thanks in advance,
