Behaviour of AD5933 at higher frequencies

Question

I seem to remember seeing documentation describing the AD5933's internal LPF somewhere, I remember it being depicted as a 3rd order filter with a cutoff somewhere between 100-120kHz. I have read through the relevant documentation but can't seem to find a section on this anywhere. 
 I'd be appreciative if somebody could point me in the right direction

There is not a single filter but a combination of filters across three stages in the Rx path. 
 
 I/V stage with a pole at 265 kHz 
 PGA with 2 poles at 350 kHz 
 ADC driver with 2 poles at 350 kHz and 2.6 MHz)
