Tool/software: WEBENCH® Design Tools
I wasn't able to select the different op amps for the different stages. Typically, the last stage with the biggest quality factor requires an op amp with much bigger GBW value, while the previous stages can be implemented with the slower and more precision op-amps. Also, this helps to save power, especially in the multichannel design. When I choose an alternative op amp that fits the 1st and 2nd stages and definitely does not fit the 3rd stage, the tool provides no warning. Moreover, it marks the 3rd stage with the green merit indicator.
Also, the tool doesn't allow to change the particular R/C component value as it was in the old good FilterPro program: after that FilterPro will adjust other components - just for this stage - in order to get the target parameters for this stage. It's a good stage-by-stage/module approach.
