I need to know the filters sequence for our application. The AD7762 has 3 filters. The first 2 are simple decimation filter (if I understand it right). The 3rd filter is a FIR and decimation filter with fixed decimation of 2. Is the decimation applied before or after the filter? Maybe I don't understand the 3rd filter. It makes a big difference for our application. Figure 31 in the datasheet shows a bandwidth responce of 625kHz, does it mean that the decimation of 2 is applied after passing through the FIR?
