ADXL312 Internal Digital Filter

On previous projects we have used a raw accelerometer signal which is sampled by a microprocessor ADC, then filtered using an embedded c-code FIR filter (8-tap, 5Hz, LP Butterworth, 2nd Order). I now want to use the ADXL312 to do the same thing, but I need to know what are the characteristics of the internal digital filter?


Also, we had external components acting as an analogue filter to counteract aliasing. I would like to know if there is any analogue filtering within this device?
